5x2 + 9x + 4 = (x + 1)(5x + 4).
9x + 4 - x + 8 = 8x + 12
9x + 4 = 6 9x = 6 -4 9x = 2 x = 2/9
Remember that slope-intercept form is: y = (slope)x + b 9x - 7y = 4 1) First, subtract 9x on both sides. -7y = -9x + 4 2) Then, divide both sides by -7. y = 9/7x + 4 3) There is your answer: y equals nine sevenths x plus 4.
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
102 +9x +4 = 9x + 106, which is in its simplest form.
8x-4
11 + 9X
5x2 + 9x + 4 = (x + 1)(5x + 4).
81x2 + 72x + 16 = 81x2 + 36x + 36x + 16 = 9x(9x + 4) + 4(9x + 4) = (9x + 4)2
It is (x+4)(x+5) when factored
9x + 4 - x + 8 = 8x + 12
9x + 4 = 6 9x = 6 -4 9x = 2 x = 2/9
-9x + 4 = -50 -9x = -50 - 4 -9x = -54 -x = -6 x = 6.
