Firstly, simplify the numerator by factorising the quadratic, to give a numerator of (3x+2)(x-1). Now, divide through by (x-1), to give (3x+2).
We need the equation in the form (x+a)(x+b)=0. The numbers in the brackets (a and b) must multiply together to get the constant at the end of the equation, in this case 12. The numbers (a and b) must add ...
A quadratic equation will always take the form ax2 + bx + c, where x is a variable and a, b and c are numbers. The equation may be given to you with several x2 values, several x valu...
