for the second half of the question you need to distribute the negative sign. so it becomes: (-7x^2+2x+3) so the full equation now is (-5x^2+2x-5)-(-7x^2+2x-3) Then you subtract life terms. So it is: -5x^2-(-7x^2)=2x^2 then: 2x+2x=4x then: -5-(-3)=2 so it would come out to: 2x^2+4x-2
ok so what about the first half
of the equation?
yes does it stay the same
yes. the negative sign only affects the second half of the equation.
so it thats the whole problem or is more needed to be done
BUT you only distribute the negative sign when its a subtraction problem, not addition. and yes. the answer at the bottom is the full answer.
ok so if it is addition you leave it as it is
yesss. i did the equation horizontally, but it might be easier to do it vertically. look at the problem like this\[-5x^2+2x-5\over7x^2-2x-3\] think of the line in the middle as the line that tells you to subtract. since all the like terms are lined up it makes it easier.
make more sense?
Now i have a question about another problem
