3x2-10=20 x2-5x 2=0 x2 10x-16=0

Question

Can someone PLEASE help me solve the above equations? Again, the problems:

3x2-10=20 (the 2 after the x is supposed to mean the 3x squared)

x2-5x 2=0 (the 2 after the first x is supposed to mean x squared)

x2 10x-16=0 (the 2 after the first x is supposed to mean x squared)

I have an idea that the second equation is prime and the last one is {2, 8}, but I'm not sure. PLEASE HELP!

Answer 1

5(x+2)+5x+10
