7 r^{2} - 10 = 25

r = 5, r = - 5

Decimal Notation

r = 2.23606 \dots, r = - 2.23606 \dots

Solution steps

7 r^{2} - 10 = 25

Move

10

to the right side

7 r^{2} = 35

Divide both sides by

7

r^{2} = 5

For

x^{2} = f (a)

the solutions are

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

r = 5, r = - 5

n - 7 \leq - 8

(5 x + 3)^{2} = 5 (x + 3)

- \frac{6}{12}

(- 4 - 5 i) (1 - i)

4 - (- \frac{z}{3}) = 8
