Factorise and solve x^2 + 3x - 4 = 0

To factorise this equation, we must find two numbers that add together to make and multiply to make -4. These numbers must be -3 and -1. We would then rewrite the equation as (x-3)(x-1)=0.

To solve this equation, we need to make either (x-3)=0 or (x-1)=0. This means that there are two solutions to this question.

x-3=0 and x-1=0

This means x=3 or x=1.
