4 b^{2} = 30 + 7 (6 + 4)

b = 5, b = - 5

Solution steps

4 b^{2} = 30 + 7 (6 + 4)

7 (6 + 4) = 70

4 b^{2} = 30 + 70

Add the numbers:

30 + 70 = 100

4 b^{2} = 100

Divide both sides by

4

b^{2} = 25

For

x^{2} = f (a)

the solutions are

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

b = 25, b = - 25

25 = 5

- 25 = - 5

b = 5, b = - 5

x^{2} - 5 x + 3 = - 8 x + 1

(w + \frac{1}{2})^{2} + 4 = 21

3 t^{2} - 6 t

3 (x - 4) (x - 1) = 0

y^{2} - 4 = 12
