Can anyone solve the following Quadratic equation by using factorising?

2xSquared - 5x - 7 = 0

Does he know how to factorise?

If he does, he simply needs to find the value of $\displaystyle x$ in each bracket seperately after factorising, so that one of the brackets is equal to $\displaystyle 0$.

In other words:

If we had $\displaystyle (x - 3)(x + 4) = 0$

Then for the first bracket $\displaystyle x - 3 = 0$ and for the second bracket $\displaystyle x + 4 = 0$ - Jan 17th 2008, 08:18 AMduckegg911
