x² + x - 12 = 0/ x² + 4x - 3x - 12 = 0 (split x into two numbers which multiply to equal -12)/ x(x + 4) - 3(x + 4) = 0 (take out x and 3 respectively)/ (x + 4)(x - 3) = 0 (collect te...

So it is easiest if we first draw out the triangle and label it.We use an equation called Pythagoras' Theorem. This equation is A^2 + B^2 = C^2So we know the length of side A (3) and side C (6), lets put ...
