(8 z + 4) (5 z + 10) = 0

z = - \frac{1}{2}, z = - 2

Decimal Notation

z = - 0.5, z = - 2

Solution steps

(8 z + 4) (5 z + 10) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

8 z + 4 = 0 or 5 z + 10 = 0

Solve

8 z + 4 = 0 : z = - \frac{1}{2}

Solve

5 z + 10 = 0 : z = - 2

The solutions to the quadratic equation are:

z = - \frac{1}{2}, z = - 2

18 x^{3} y^{2} w + 12 x^{2} y^{3} w^{2} - 24 x y^{4} w^{3}

6 (- 1 - 4 w) = - 18

\frac{( - \frac{8}{17} )}{( - \frac{15}{17} )}

- 7 + 19 - 23 - 14 + 5

\frac{( 3 + 273.15 )}{( 16 + 273.15 )}
