Simplify each of the following algebraic expressions.

(a) $$3x^2 - 6 +x+11-x^2+5x$$

(b) $$3(5x-1)-x+4$$

(c) $$\frac{x^2-16}{x-4}$$, wher $$x \neq 4$$

(d) $$(2x+5)(3x-1)$$

[Reveal] Spoiler: OA
(a) $$2x^2+6x+5$$ (b) $$14x+1$$ (c) $$x+4$$ (d) $$6x^2+13x-5$$

(a) $$3x^2 - 6 +x+11-x^2+5x=3x^2-x^2+x+5x-6+11=2x^2+6x+5$$

(b) $$3(5x-1)-x+4=15x-3-x+4=14x+1$$

(c) $$\frac{x^2-16}{x-4}=\frac{(x+4)(x-4)}{x-4}=x+4$$

(d) $$(2x+5)(3x-1)=6x^2-2x+15x-5=6x^2+13x-5$$

Cheers,
