11 - 3 r^{2} = - 49

r = 25, r = - 25

Decimal Notation

r = 4.47213 \dots, r = - 4.47213 \dots

Solution steps

11 - 3 r^{2} = - 49

Move

11

to the right side

- 3 r^{2} = - 60

Divide both sides by

- 3

r^{2} = 20

For

x^{2} = f (a)

the solutions are

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

r = 20, r = - 20

20 = 25

- 20 = - 25

r = 25, r = - 25

7 - (4 x - 3) = 9 (- 6 + 3 x)

\frac{2 x - 3}{6} = \frac{2 x}{3} + \frac{1}{2}

2 ln (4) - ln (2)

2 (2 x + 3) = x + 9

10 x - 13 \leq 4 x - 14
