x^{2} - 10 x = - 21

x = 3, x = 7

Solution steps

x^{2} - 10 x = - 21

Move

21

to the left side

x^{2} - 10 x + 21 = 0

Factor

x^{2} - 10 x + 21 : (x - 3) (x - 7)

(x - 3) (x - 7) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x - 3 = 0 or x - 7 = 0

Solve

x - 3 = 0 : x = 3

Solve

x - 7 = 0 : x = 7

The solutions to the quadratic equation are:

x = 3, x = 7
