Find the integral of 3x^2 + 4x + 9 with respect to x.
We must first remember that to integrate, we must increase the power by 1 and divide by this new power.
Therefore, to integrate 3x^2 + 4x + 9, we take the first term, 3x^2
Factorise and solve x^2 + 3x - 4 = 0
To factorise this equation, we must find two numbers that add together to make 3 and multiply to make -4. These numbers must be
