Answer:

a = 9 + b - c → D

Explanation:

To cancel the square root of one side of an equation square the two sides

Examples:

If
√(x) = 5, to find x square the two sides to cancel the square root

(
√(x) )² = (5)², then x = 25

If
√(a+b) = 7, to find a + b square the two sides to cancel the square root

(
√(a+b) )² = (7)², then a + b = 49

Now let us solve the question

To solve it for a square the two sides then keep a on the left side and move b, c to the other side


√(a-b+c) = 3

→ Square the two sides to cancel the square root

∴ (
√(a-b+c))² = (3)²

a - b + c = 9

→ Add b to both sides to move b from the left side to the right side

∴ a - b + b + c = 9 + b

a + c = 9 + b

→ Subtract c from both sides to move c from the left side to the right side

∴ a + c - c = 9 + b - c

a = 9 + b - c
