solve: x2 = 8x – 12

Question

solve:  x2 = 8x – 12

anonymous · Answer

-xˆ2 - 8x - 12

Step 1: Equal to zero

-xˆ2 - 8x - 12 = 0

Step 2: Multiply by -1 to both sides of the equation to get all positive numbers.

xˆ2 + 8x + 12 = 0

Step 3: Factorize

(x + 2)(x + 6) = 0

Step 4: Take each term separately and solve for x:

(x + 2) = 0 ==> x = -2

(x + 6) = 0 ==> x = -6

Solution:

x = -2
or
x = -6

Hope I helped!
