7 w^{2} = 448

w = 8, w = - 8

Solution steps

7 w^{2} = 448

Divide both sides by

7

w^{2} = 64

For

x^{2} = f (a)

the solutions are

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

w = 64, w = - 64

64 = 8

- 64 = - 8

w = 8, w = - 8

x^{2} - 51 = 14 x

x^{2} + 20 x + 28 = 0

x (4 x + 7) = 2

2 x^{2} + 30 = 16 x

4 - x^{2} = 1 - \frac{1}{4} x^{2}
