A (x) = - x (x - 80)

x = 0, x = - A + 80

Solution steps

A (x) = - x (x - 80)

Move

x (x - 80)

to the left side

A x + x (x - 80) = 0

Factor

A x + x (x - 80) : x (A - 80 + x)

x (A - 80 + x) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or A - 80 + x = 0

Solve

A - 80 + x = 0 : x = - A + 80

The solutions to the quadratic equation are:

x = 0, x = - A + 80

(x + 2)^{2} - 16 = 0

3^{2} = 1^{2} + x^{2}

3 y^{2} - 3 = 0

x^{2} - 2 x - 15 = 0

x^{2} - 4 x - 12 = 0
