Complete the Square : -2^2 + 8x + 73 = 9 I got (x-2)^2 = 35 but DeltaMath is not accepting my answer. Thank you!!

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

-2^2+8*x+73-(9)=0

Step by step solution :

STEP1:

Equation at the end of step1:

(((0 - 22) + 8x) + 73) - 9 = 0

STEP2:

STEP3:

Pulling out like terms

3.1 Pull out like factors :

8x + 60 = 4 • (2x + 15)

Equation at the end of step3:

4 • (2x + 15) = 0

STEP4:

Equations which are never true:

4.1 Solve : 4 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

4.2 Solve : 2x+15 = 0

Subtract 15 from both sides of the equation :

2x = -15

Divide both sides of the equation by 2:

x = -15/2 = -7.500

One solution was found :

x = -15/2 = -7.500

X= -15/2.        (Rewriten equation : 2x= -15) HOPE THAT HELPED!!!
