Can anyone solve the following Quadratic equation by using factorising?
2xSquared - 5x - 7 = 0
Cheers
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 $\displaystyle x + 4 = 0$
See this thread.
