Find the value of the polynomial $5x - 4x^2 + 3$ at $x = 0$.

Verify whether the following are zeroes of the polynomial indicated against them:
$p(x) = (x + 1)(x - 2)$,$x = -1, 2$

Factorise: $12 x^{2}-7 x+1$

Which of the following expressions are polynomials in one variable and which are not? State reasons for your answer: $4 x^{2}-3 x+7$.

Use suitable identities to find the products: $(x+8)(x-10)$

Find the following products using appropriate identities:
$(i) (x + 3) (x + 3)$
$(ii) (x - 3) (x + 5)$
