25 r^{2} + 7 = 107

r = 2, r = - 2

Solution steps

25 r^{2} + 7 = 107

Move

7

to the right side

25 r^{2} = 100

Divide both sides by

25

r^{2} = 4

For

x^{2} = f (a)

the solutions are

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

r = 4, r = - 4

4 = 2

- 4 = - 2

r = 2, r = - 2

6 x^{2} + 5 x + 8 = 0

a, (a + b)^{3} = a^{3} + b^{3}

x^{2} = 3 x - 4

x, (x - 5)^{2} - (y + 3)^{2} = 0

3 x^{2} - 5 x - 10 = x^{2} + 3 x + 14
