b.The solution is x=7.
c.No values of x make the equation true.
d.All values of x make the equation true
we have the equation
solve for x
Apply distributive property right side
Combine like terms
subtract 4x both sides
The equation has infinity solutions
.All values of x make the equation true
Answer:
x = 8 ± 2i
Step-by-step explanation:
Given
x² - 16x + 60 = - 12 ( subtract 60 from both sides )
x² - 16x = - 72
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 8)x + 64 = - 72 + 64, thus
(x - 8)² = - 8 ( take the square root of both sides )
x - 8 = ± = ± 2i
( add 8 to both sides )
x = 8 ± 2i
