Use suitable identities to find the products : $(3-2 x)(3+2 x)$
$(3-2 x)(3+2 x)$
Using the identity $(a+b)(a-b)=a^{2}-b^{2},$ we have :
$(3-2 x)(3+2 x)=(3)^{2}-(2 x)^{2}=9-4 x^{2}$
Find a zero of the polynomial $p(x) = 2x + 1$.
Factorise : $2 x^{2}+7 x+3$
Factorise $y^2 -5y + 6$ by using the Factor Theorem.
