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 :
$(3-2 x)(3+2 x)=(3)^{2}-(2 x)^{2}=9-4 x^{2}$
Factorise the following using appropriate identities : $4 y^{2}-4 y+1$
Write the following cubes in expanded form : $\left[\frac{3}{2} x+1\right]^{3}$
Find the degree of the polynomials given : $2-y^{2}-y^{3}+2 y^{8}$
Find the zero of the polynomial : $p(x) = x -5$
Write the coefficients of $x^2$ in each of the following :
