Factor 62x² - 99x + 37

Here we will show you how to factor the quadratic function 62x² - 99x + 37 using the box method. In other words, we will show you how to factor 62x squared minus 99x plus 37 (62x^2 - 99x + 37) using the box method. It is a 5-step process:

Step 1: The standard form of a quadratic equation is ax² + bx + c. We start by labeling the different parts of our equation 62x² - 99x + 37, like this:

a = 62
b = -99
c = 37

Step 2: Next, we need to draw a box and divide it into four squares:

-1	-62x	37
x	62x²	-37x
	62x	-37

We put 62x² (a) in the bottom left square and 37 (c) in the top right square, like this:

-1	-62x	37
x	62x²	-37x
	62x	-37

Step 3: In order to fill in the other two squares, we need to do some math. We have to find two numbers that multiply together to give us the product of 62 times 37 (a × c), and add together to equal -99 (b).

More specifically, 62 times 37 is 2294. Therefore, we need to find the two numbers that multiply to equal 2294, and add to equal -99.

? × ? = 2294
? + ? = -99

After looking at this problem, we can see that the two numbers that multiply together to equal 2294, and add together to equal -99, are -62 and -37, as illustrated here:

-62 × -37 = 2294
-62 + -37 = -99

Now, we can fill in the last two squares in our box with -62x and -37x. Place -62x in the upper left square, and place -37x in the lower right square.

-1	-62x	37
x	62x²	-37x
	62x	-37

Step 4: Next, we need to find four final numbers to finish factoring our equation. We can see that our box is a 2 x 2 table made up of rows and columns.

Our goal is to find the numbers that, when multiplied together, result in the products in each square. We can do this by finding the greatest common factor in each row.

Let’s look at the top row. We have the terms -62x and 37. The greatest common factor of -62x and 37 is -1. Therefore, we write -1 to the left of the top row. You can see it here in the color green:

-1	-62x	37
x	62x²	-37x
	62x	-37

Next, let’s look at the bottom row. We have the terms 62x² and -37x. The greatest common factor of 62x² and -37x is x. Therefore, we write x to the left of the bottom row. You can see it here in the color blue:

-1	-62x	37
x	62x²	-37x
	62x	-37

To find the values below the table, we first divide 62x² by x (labeled in blue). This gives us 62x.

62x² ÷ x = 62x

You can see this value colored in orange below:

-1	-62x	37
x	62x²	-37x
	62x	-37

Next, we divide -37x by x (labeled in blue). This gives us -37.

-37x ÷ x = -37

You can see this value colored in purple below:

-1	-62x	37
x	62x²	-37x
	62x	-37

Step 5: Now we have all of the information we need to finish factoring the equation. The values outside of the box are used to factor 62x² - 99x + 37. You simply put the values on the left in one set of parentheses, and the values below in another set of parentheses, to get the answer:

(x - 1)(62x - 37)

That’s it! Now you know how to factor the equation 62x² - 99x + 37.
