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)

3030 ur welcome

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
