(f+g)(x)=0
f (x) + g (x)=0

now,
substitute their values

x^2 -4x + x -18 = 0
x^2 -3x -18 =0
x^2 - 6x + 3x - 18 =0
x (x-6) + 3 (x-6) = 0
(x-6)(x+3) = 0

we have to find it's zeroes (or roots) now:

x-6 =0
x = 6

x +3 =0
x = -3

liberstina [14]

Answer:

$\pink{ - 1 \frac{7}{9} }$

Step-by-step explanation:

$( \frac{2}{5} \div \frac{3}{8} ) \div ( - \frac{3}{5} ) \\ (\frac{2}{5} \times \frac{8}{3} ) \times ( - \frac{5}{3} ) \\ \frac{16}{15} \times - \frac{5}{3} \\ - \frac{80}{45}$

As the answer can be more simplified, divide both numerator and denominator by 5.

$- \frac{16}{9} = - 1 \frac{7}{9}$
