Question

Solve for x.
Enter the solutions from least to greatest.
—4x2 – 7 = -11
lesser x =
greater x =

Answer 1

Answer:

lesser x = - 1 , greater x = 1

Step-by-step explanation:

- 4x² - 7 = - 11 ( add 7 to both sides )

- 4x² = - 4 ( divide both sides by - 4 )

x² = 1 ( take square root of both sides )

x = ± $\sqrt{1}$ = ± 1

then

lesser x = - 1

greater x = 1
