90 π = π x (x + 8 + x)

x = 5, x = - 9

Solution steps

90 π = π x (x + 8 + x)

Move

π x (x + 8 + x)

to the left side

90 π - π x (x + 8 + x) = 0

Factor

90 π - π x (x + 8 + x) : - 2 π (x - 5) (x + 9)

- 2 π (x - 5) (x + 9) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x - 5 = 0 or x + 9 = 0

Solve

x - 5 = 0 : x = 5

Solve

x + 9 = 0 : x = - 9

The solutions to the quadratic equation are:

x = 5, x = - 9

4 g^{2} + 12 g + 9

\frac{1}{3} x - 2 = 2

5 (d + 4) = 2 (2 d - 1)

9 (2 x)^{2} - 2 = 0

- 7 (- a^{2}) (- b^{3})
