5x2-18x+9 = (5x-3)(x-3)
18x + 45 or 9(2x + 5) how is this answer figured?
9(2x + 5)
5x² - 18x + 9 = (5x² - 15x) - (3x - 9) = 5x(x - 3) - 3(x - 3) = (5x - 3)(x - 3).
18x + 24 6(3x + 4) is factored fully
5x2-18x+9 = (5x-3)(x-3)
5x2-46x+9 = (5x-1)(x-9)
18x + 45 or 9(2x + 5) how is this answer figured?
7Improved Answer:8x2-18x+9 = (4x-3)(2x-3)
10x2-36x+18 Divide all terms by 2: 5x2-18x+9 = (5x-3)(x-3) when factored
Because: (9-x)(9-x) = 81-18x+x^2
x2-18x+81 = (x-9)(x-9) when factored
The vertex is (-9, -62).
9(2x + 5)
Yes.
