16x2 + 32x - 65 = 0 factorises (4x + 13)(4x - 5) This makes x either -13/4 or 5/4.
4x + 32x + 9 = 36x + 9
32x + 8 β 34x
If 32X + 53 = 501, then 32X = 448, and X = 448/32 = 14.
35x + 10
16x2 + 32x - 65 = 0 factorises (4x + 13)(4x - 5) This makes x either -13/4 or 5/4.
It is 6x(2x+5) when factored
4x + 32x + 9 = 36x + 9
(x - 5)(5x - 7)
32x + 8 β 34x
If 32X + 53 = 501, then 32X = 448, and X = 448/32 = 14.
35x + 10
That's pretty easy. Just add the like terms (2x and 32x) and keep the 3. You get 34x plus 3.
Isolating xx = (6+6)/32x = 0.375
