Question

Make x the subject:y= (x+10)^2​

Answer 1

Answer:

x = - 10 ± $\sqrt{y}$

Step-by-step explanation:

y = (x + 10)² , or

(x + 10)² = y ( take square root of both sides )

x + 10 = ± $\sqrt{y}$ ( subtract 10 from both sides )

x = - 10 ± $\sqrt{y}$

Answer 2

Y= (x+10)^2
Root both sides
±√y=x+10
-10
x= ±√y -10
