    x^2+4x-60=0
    You have to look for two numbers that multiply to the last term (-60) and add to the middle term (4). In this case, the numbers are 10 and -6. We write them like this:
    (x+10)(x-6)
    Check my work.

  • 10th grade -

    2x + 4x=60
    6x=60
    x=60/6
    so x=10
    very simple.....
