- 2 (x - 9) (x + 7) = 0

x = 9, x = - 7

Solution steps

- 2 (x - 9) (x + 7) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x - 9 = 0 or x + 7 = 0

Solve

x - 9 = 0 : x = 9

Solve

x + 7 = 0 : x = - 7

The solutions to the quadratic equation are:

x = 9, x = - 7

y^{2} = - 2

\frac{5}{80}

2 x^{2} - 3 x \leq 1 - 5 x

∣ 4 x - 6 ∣ = 34

f = 1^{3} - 9 \cdot 1
