x^{2} - 20 = 0

x = - 25, x = 25

Decimal Notation

x = - 4.47213 \dots, x = 4.47213 \dots

Solution steps

x^{2} - 20 = 0

Factor

x^{2} - 20 : (x + 25) (x - 25)

(x + 25) (x - 25) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x + 25 = 0 or x - 25 = 0

Solve

x + 25 = 0 : x = - 25

Solve

x - 25 = 0 : x = 25

The solutions to the quadratic equation are:

x = - 25, x = 25

16 = 4 x^{2}

(5 x - 40)^{2} = 75

2 x^{2} + x = 0

y, x^{2} + y^{2} = 36

9 x^{2} - 6 x - 35 = 0
