An expression is shown below: 3x3y + 15xy − 9x2y − 45y part a: rewrite the expression so that the gcf is factored completely. show the steps of your work. (4 points) part b: rewrite the expression completely factored. show the steps of your work.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
