-3x2+10x-3 -(3x2-10x+3) -(3x-1)(x-3)
3x2 if it is in parentheses
-6to work it out: remember BIDMASso 3x2=6! then 6-12=-6
(2x3)+(3x5)-(3x2)= 2x3=6 3x5=15 3x2=6 So..... 6x25-6= 6x25=150 150+6=156
Set the equation equal to zero. 3x2 - x = -1 3x2 - x + 1 = 0 The equation is quadratic, but can not be factored. Use the quadratic equation.
