9600 = 40 r \cdot r

r = 415, r = - 415

Decimal Notation

r = 15.49193 \dots, r = - 15.49193 \dots

Solution steps

9600 = 40 rr

Switch sides

40 rr = 9600

Simplify

40 r^{2} = 9600

Divide both sides by

40

\frac{40 r ^{2}}{40} = \frac{9600}{40}

r^{2} = 240

For

x^{2} = f (a)

the solutions are

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

r = 240, r = - 240

240 = 415

- 240 = - 415

r = 415, r = - 415

w^{2} - 10 w + 40 = 0

\frac{- 8}{- 2}

2 x^{2} - 5 x < - 3

- x^{2} + 6 x = 8

- 4 (x + 8) - 2 x = 25
