Choose all of the equations that are true.

x2 + 2x − 24 = (x + 6)(x − 4)
x2 − 8x + 15 = (x + 5)(x + 3)
3x2 + 4x + 1 = (3x + 1)(x + 1)
5x2 − 2x − 3 = (5x + 3)(x − 1)
4x2 − 49 = (2x − 7)(2x + 7)

I think it's only D

Step-by-step explanation:

4x2-49=(2x-7)(2x+7)

2x*2x=4x2

-7*7=-49,which makes the answer 4x2-49

Step-by-step explanation:

These is True

x² + 2x − 24 =x² -4x+6x− 24=x(x-4)+6(x-4)=(x + 6)(x − 4)

3x² + 4x + 1 = 3x² + 3x+x + 1= 3x(x+1)+1(x+1)=(3x + 1)(x + 1)

5x² − 2x − 3 = 5x² − 5x+3x − 3= 5x(x-1)+3(x-1)=(5x + 3)(x − 1)

4x² − 49 = 4x² − 7²= (2x-7)² = (2x − 7)(2x + 7)

These is False

x² − 8x + 15 = x² − 5x-3x + 15= x(x-5)-3(x-5)=(x-5)(x-3)

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
