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.

16/40 and 35/40 is right. 16/40-35/40=? Do 16-35, use a calculator if you need to. That's your numerator (top number of a fraction). The 40 is your denominator (bottom number).
