Question

x²-1/x²+4x+3÷ x³-1/x²+x+1 rational algebraic expression with a concrete solutions​

Answer 1

Answer:

Simplify (x² – 2x) / (x + 2) * (3 x + 6)/ (x – 2)

Solution

Factor the numerators,

(x² – 2x) / (x + 2) * (3 x + 6)/ (x – 2)

⟹ x (x – 2) / (x + 2) * 3(x + 2)/ (x – 2)

Cancel out common terms in numerators and denominators of both fractions to get;

⟹ 3x.

not sure about the answer but hope it hepls u ☺
