5x-8 + 7x 12x-8 12x = 8 x = 8/12 x= 2/3
7x^3. That is 7x cubed.... or 7x*7x*7x (where * means multiply). You should get 343x
2x2 + 7x - 15 = 02x2 + 10x - 3x - 15 = 0(2x2 - 3x) + (10x - 15) = 0x(2x - 3) + 5(2x - 3) = 0(2x - 3)(x + 5) = 0(2x - 3) = 0 or (x + 5) = 0x = 3/2 or x = -5
14x2 + 29x - 15= 14x2 + 35x - 6x - 15= 7x(2x + 5) - 3(2x + 5)= (2x + 5)(7x - 3)
what is -12X squared +28X - 15? i figured it out myself. its (-6X + 5)(2X - 3).
