Quizplus · Accepted Answer

To multiply the given expressions, use the distributive property (FOIL method): $(-1+3x)(5+3x) = -1*5 + -1*3x + 3x*5 + 3x*3x = -5 -3x + 15x + 9x^2 = 9x^2 + 12x - 5$.

Multiply - (−1+3x)(5+3x)(-1+3 \mathrm{x})(5+3 \mathrm{x})(−1+3x)(5+3x) A) 3x2+12x+123 x^{2}+12 x+123x2+12x+12 B) 9x2+12x−59 x^{2}+12 x-59x2+12x−5
