45 = 5 r^{2}

r = 3, r = - 3

Solution steps

45 = 5 r^{2}

Switch sides

5 r^{2} = 45

Divide both sides by

5

r^{2} = 9

For

x^{2} = f (a)

the solutions are

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

r = 9, r = - 9

9 = 3

- 9 = - 3

r = 3, r = - 3

6 x^{2} + 100 = 0

x^{2} - x - 56 = 0

15 n^{2} + 6 n - 8 = 4 n

y, 4 y^{2} - 12 x y + 10 x^{2} + 2 x + 1 = 0

z^{2} + 10 z - 24 = 0
