How do you Identify the solutions to the equation #2x^2+5x=3# when you solve by factoring?
Firstly we note that it is a quadratic.( has
Find factors of 2 and 3 which subtract to give 5.
The signs will be different, there must be more positives.
As both 2 and 3 are prime numbers there are only 2 possibilities.
Cross multiply the factors:
we have the correct factors, now put in the correct signs.
The factors are:
One of the factors must be 0 to give a product of 0.
