−10x + 1 + 7x = 37 x = −15 x = −12 x = 12 x = 15

x = -12

Step-by-step explanation:

−10x + 1 + 7x = 37

Combine like terms

-3x+1 = 37

Subtract 1 from each side

−3x + 1 -1 = 37-1

-3x = 36

Divide each side by -3

-3x/-3 = 36/-3

x = -12

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
