Q:
# Factor these expressions.x^2 + 7x + 10x^2 - 3x + 2-x^2 + 3x + 409y^2 - 36-x^2 + 5x - 4

Accepted Solution

A:

Hello There!

(x + 2)(x + 5)

To check you can expand it:

x² + 2x + 5x + 10

= x² + 7x + 10

So we know it is correct.

(x - 2)(x - 1)

To check you can expand it:

x² - 2x - x + 2

= x² - 3x +2

So we know it is correct

-(x + 5)(x - 8)

To check you can expand it:

-x² - 5x + 8x + 40

-x² + 3x + 40

So we know it is correct

9(y + 2)(y - 2)

To check you can expand it:

9y² - 36

So we know it is correct.

-(x - 1)(x - 4)

To check you can expand it:

-x² + 5x - 4.

So we know it is correct.

Hope This Helps You!

Good Luck :)
