(2x + 1)(x + 4)
As written, -5x + 9x = 4x 4x - 4 = 4(x - 1) If that's -5x2 + 9x - 4, that factors to -(x - 1)(5x - 4)
Let the symbol ^ mean "to the power" Then 9x^2 + 24x + 16 = (3x + 4)(3x +4) = (3x + 4)^2
Assuming it's a plus sign, that factors to (2x + 1)(x + 4)
11 + 9X
-5x2+9x-4 -5x2+9x+-4 Factors of -20 that add to equal 9 are -5 and-4 -5x2+5x+4x+-4 -5x(1x+1) + 4x(1+-1x)
the answer is (3x-2)(9x squared+6x+4)
(3x - y+ 2)(3x + y + 2)
5x2 + 9x + 4 = (x + 1)(5x + 4).
81x2 + 72x + 16 = 81x2 + 36x + 36x + 16 = 9x(9x + 4) + 4(9x + 4) = (9x + 4)2
x - 4. x^2 + 5x - 36 = (x - 4) (x + 9) x^2 - 9x + 20 = (x - 4) (x - 5)
9x + 4 - x + 8 = 8x + 12
