Answer:
Explanation:
To make x the subject of y = ax^2 + b, we can use the following steps:
1.Subtract b from both sides to isolate the term with x^2:
y - b = ax^2
2.Divide both sides by a to isolate x^2:
(y - b) / a = x^2
3.Take the square root of both sides to solve for x:
x = ± sqrt((y - b) / a))
Therefore, the expression for x as a subject of y = ax^2 + b is:
x = ± sqrt((y - b) / a))
