a^{2} - 2 a = 63

a = - 7, a = 9

Solution steps

a^{2} - 2 a = 63

Move

63

to the left side

a^{2} - 2 a - 63 = 0

Factor

a^{2} - 2 a - 63 : (a + 7) (a - 9)

(a + 7) (a - 9) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

a + 7 = 0 or a - 9 = 0

Solve

a + 7 = 0 : a = - 7

Solve

a - 9 = 0 : a = 9

The solutions to the quadratic equation are:

a = - 7, a = 9

\frac{1}{2} x^{2} + 2 x + \frac{1}{10} = 0

10 x^{2} + 15 x + 7 = 0

4 (x^{2} - 9) - 8 = - 19

b, \frac{b ^{2}}{2} - \frac{t ^{2}}{8} = 1

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