Factorise this equation: x^2+3x-10=0

The first stage is to calculate two numbers that multiply together to make the integer in the equation, in this example it's -10. The numbers are 5 and 2. Now these two number should both satisfy the signs (+ and - ) and add together to produce the number before the with the single x, in this case +3. Therefore the answer is as follows; (X+5)(X-2).
