solve for

r, A = 4 r^{2}

r = \frac{A}{2}, r = - \frac{A}{2}

Solution steps

A = 4 r^{2}

Switch sides

4 r^{2} = A

Divide both sides by

4

r^{2} = \frac{A}{4}

For

x^{2} = f (a)

the solutions are

x = f (a), - f (a)

r = \frac{A}{4}, r = - \frac{A}{4}

Simplify

\frac{A}{4} : \frac{A}{2}

Simplify

- \frac{A}{4} : - \frac{A}{2}

r = \frac{A}{2}, r = - \frac{A}{2}

y^{2} - 8 y - 4 = 0

b^{2} - 10 b + 21 = 0

x (2 x - 3) = 18

- 5 x^{2} + 60 x - 405 = 0

- 3 b^{2} + b - A = 0
