For the polynomial, solve P(x)=0
$\displaystyle P(x)=(3x+2)(x-1)(4x+5)$
how do i solve this question?
Thanks in advance
if
$\displaystyle
P(x)=(3x+2)(x-1)(4x+5) = 0
$
then either:
1. $\displaystyle 3x+2 = 0$
or
2. $\displaystyle x-1 = 0$
or
3. $\displaystyle 4x+5 = 0$
or every combination of the above thus the solution follows immediately:
$\displaystyle
x = - \frac{2}
{3},1, - \frac{5}
{4}
$
