Answer:

below

Step-by-step explanation:

= 15x^2+2x-8

= 15x^2+12x+10x-8

= 3x(5x-4)+2(5x-4)

= (3x+2) (5x-4)

3x+2= 0    OR 5x-4 =0

x= -2/3 , 4/5

Answer:

\large \text{$p(x)=(5x+4)(3x-2)$}

Step-by-step explanation:

Given :

\large \text{$p(x)=15x^2+2x-8$}

We have to factorize the p ( x )

By splitting mid term method we get

\large \text{$p(x)=15x^2+2x-8$}\\\\\\\large \text{$p(x)=15x^2+12x-10x-8$}\\\\\\\large \text{$p(x)=3x(5x+4)-2(5x+4)$}\\\\\\\large \text{$p(x)=(5x+4)(3x-2)$}

Zeroes of p ( x )

\large \text{$p(x)=(5x+4)(3x-2)$}\\\\\\\large \text{$(5x+4)=0 \ or \ (3x-2)=0$}\\\\\\\large \text{$(5x)=-4 \ or \ (3x)=2$}\\\\\\\large \text{$x=\dfrac{-4}{5} \ or \ x=\dfrac{2}{3}$}

Thus we factorize and get zeroes too.
