Give possible expressions for the length and breadth of the rectangle whose area is given by $4 a^{2}+4 a-3$

For the polynomial $p(x)=x^{2}-7 x+12$ $p(2)=\ldots \ldots . .$

Is $x+1$ is a factor of $4 x^{3}+7 x^{2}-2 x-5$ or not ?

By remainder Theorem find the remainder, when $p(x)$ is divided by $g(x),$ where

$p(x)=4 x^{3}-12 x^{2}+14 x-3, g(x)=2 x-1$

Write the coefficient of $x^{2}$ in the following polynomials

$5-7 x-3 x^{2}$
