Q:
# Five less than twice what negative number squared is 157?

Accepted Solution

A:

Five less than twice what negative number squared is 157 <- put into an expression

-5 + 2(-x^2) = 157

Now simplify:

-5 + -2x^2 = 157

-2x^2 = 162

-2x^2 - 162 = 0

2x^2 + 162 = 0

x^2 + 81 = 0

-5 + 2(-x^2) = 157

Now simplify:

-5 + -2x^2 = 157

-2x^2 = 162

-2x^2 - 162 = 0

2x^2 + 162 = 0

x^2 + 81 = 0
