x^{2} - 3 x = 40

x = - 5, x = 8

Solution steps

x^{2} - 3 x = 40

Move

40

to the left side

x^{2} - 3 x - 40 = 0

Factor

x^{2} - 3 x - 40 : (x + 5) (x - 8)

(x + 5) (x - 8) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x + 5 = 0 or x - 8 = 0

Solve

x + 5 = 0 : x = - 5

Solve

x - 8 = 0 : x = 8

The solutions to the quadratic equation are:

x = - 5, x = 8

80% o f 60

6.5%

x, 3 x = 1

\frac{( 84 )}{( 7 )}

x^{2} - 6 x - 40 = 0
