Factorising means reducing an equation to a set of brackets, in the form (x+a)(x+b), where a and b are constants. To factorise this equation, we must find two numbers that add to make -6, and multiply to ...
When looking at this equation, we need to think of two numbers that multiply together to give 12 and have a difference of one. We can rewrite the equation as the following: (x-4)(x+3) = 0 Solving for x:Th...
3(x+1) - 2(x-1) = 1(x-1)(x+1)3x + 3 - 2x + 2 = x2 - 1x2 - x - 6 = 0(x - 3)(x + 2) = 0x = 3 x = -2
Begin by setting up the equations simultaneously. To make it easier we can label the equations (1) and (2)3y-2x=11 (1)y+x=12 (2)We then need to make the values of y or the values of x equal in both equati...
The quadratic formula is used to find the roots of a quadratic equation which comes in this form:y = ax2 + bx + cBy finding the roots, we mean that we find the values of...
