Multiply the binomials $$(2x + 5)$$ and $$(4x - 3)$$

Using identities, evaluate $$8.9^2$$.

Using identities, evaluate $$12.1^2 -7.9^2$$.

Using $$(x + a) (x + b) = x^2+(a+b)x+ab$$, find $$103 \times 104$$.

Simplify: $$(7m -8n)^2 + (7m + 8n)^2$$.

Using identities, evaluate $$5.2^2$$.

Simplify $$(x^2-5)(x+5)+ 25$$

Simplify: $$(a^2 + 5)(b^3 + 3) + 5$$

$$3x \times (4x + 2)$$

$$(4x + 1)(4x - 1) =$$
