Question

simplified form of (2x^2+ 8x - 42)/(x^2 + 12x + 35)? (show restrictions and how you did it plz)

Answer 1

Can you factor the numerator?

Answer 2

Just as an easier way to read it:
\[\frac{2x^{2}+8x-42}{x^{2}+12x+35}\]

After you factor it, keep in mind:
\[(aX+c)(bX+d) = abX^{2} + adX + bcX + cd = abX^{2} + (ad + bc)X + cd = \]
