9 - 10 r^{2} = - 931

r = 94, r = - 94

Decimal Notation

r = 9.69535 \dots, r = - 9.69535 \dots

Solution steps

9 - 10 r^{2} = - 931

Move

9

to the right side

- 10 r^{2} = - 940

Divide both sides by

- 10

r^{2} = 94

For

x^{2} = f (a)

the solutions are

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

r = 94, r = - 94

\frac{1}{3} \cdot 3

x - 3 > 3 (x - 1)

∣ x - 1 ∣ \geq - 3

∣ 2 x - 3 ∣ = ∣ 6 x - 3 ∣

4 x - 3 > 9 or - 8 x \geq 16
