8y-7x
This quadratic expression can be arranged as: -x2+7x+12 When factorised: (-x+8.424428901)(x+1.424428901) So the intercepts are: x = 8.424428901 or x = -1.424428901 The above was worked out by using the quadratic equation formula.
2x+7x-10=4x+3-2x 9x-10=2x+3 7x=13 x=13/7ans
(-7x + 3)(-7x +3)
-4x-1-3x-4+5 = -7x-1-2x+1+6 -7x = -9x+6 2x = 6 x = 3
x2 + 7x - 56 cannot be factorised.

It is: x-1+4+7x-3 = 8x simplified
2x+7x-10=4x+3-2x 9x-10=2x+3 7x=13 x=13/7ans
(-7x + 3)(-7x +3)
-4x-1-3x-4+5 = -7x-1-2x+1+6 -7x = -9x+6 2x = 6 x = 3
Minus 61 (-61)
4x - 7 = 5 + 7x x = -4
No
49x2 - 84x + 36 = (7x - 6)(7x - 6) or (7x - 6)2
