Solve for a. sqrt –4a = sqrt ( 4 − 2a) a = _____

Square Both Sides: Square both sides of the equation to eliminate the square roots. (sqrt(−4a))^2 = (sqrt(4 − 2a))^2 −4a = 4 − 2aAdd 2a: Add 2a to both sides of the equation to get all the terms with 'a' on one side. −4a + 2a = 4 − 2a + 2a −2a = 4Divide by -2: Divide both sides by -2 to solve for 'a'. −2a / -2 = 4 / -2 a = -2

Q. Solve for

a

\newline

\sqrt{-4a} = \sqrt{(4 - 2a)}

\newline

a =

_____

Square Both Sides: Square both sides of the equation to eliminate the square roots. $\newline$ $(\sqrt{-4a})^2 = (\sqrt{4 - 2a})^2$ $\newline$ $-4a = 4 - 2a$
Add $2$ a: Add $2a$ to both sides of the equation to get all the terms with ' $a$ ' on one side. $\newline$ $-4a + 2a = 4 - 2a + 2a$ $\newline$ $-2a = 4$
Divide by $-2$ : Divide both sides by $-2$ to solve for $a$ . $\frac{-2a}{-2} = \frac{4}{-2}$ $a = -2$
