Thread: Solve P(x)=0.....

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}

$

thanks for your help! it really helped me complete the other questions i had easily
