Question

Solve y = x^2 +11 for x.

Answer 1

Answer:

x = ± $\sqrt{y-11}$

Step-by-step explanation:

Given

y = x² + 11 ( subtract 11 from both sides )

y - 11 = x² ( take the square root of both sides )

± $\sqrt{y-11}$ = $\sqrt{x^2}$, hence

x = ± $\sqrt{y-11}$

Answer 2

Answer:

x=square root of y-11 or x=-square root of y-11
