3x^2-22x-40 + 2/3x^2-16x + 20 add and simplify

can some one show me what im doing to help me solve this problem because this is due by midnight and i do not understand this.

Answer 1

I see the 2/3 as a fraction coefficent of x^2 . If so, then

x^2(3+2/3)-x(22+16) -40 + 20

so what is the answer? I am not understanding what you don't know about it.

Answer 2

its supposed to be 1 over 3x^2-22x-40 + 2 over 3x^2-16x+ 20 and i don't understand, i mean am i supposed to croos out the 3x^2 because its on both sides?

Answer 3

Both sides? Both sides of what?

Answer 4
