∙ 2012-02-10 10:27:25-5x2+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)
5x2 + 9x + 4 = (x + 1)(5x + 4).
= 5x2+70-16+9x-2 = 5x2+9x+52 = 5x2+9x1+52 This implies coefficient of degree 1 is 9. Ans.
As written, -5x + 9x = 4x 4x - 4 = 4(x - 1) If that's -5x2 + 9x - 4, that factors to -(x - 1)(5x - 4)
i thinking this answer should be -20
102 +9x +4 = 9x + 106, which is in its simplest form.
3x2 + 9x 3x(x + 3) -------------
5*2+9x-2=0 so, going by BODMAS rule 10+9x-2=0 9x=-10+2 9x=-8 x=-8/9 I think!!
You don't need to factor that; you can add them together, since they have the same variable.However, assuming you might mean 81x squared + 9x, you can take out the common factor, which is 9x.
10 + 9x
9(9x + 2)
-11x + 13
