add the following
(-8x^2-2x+4)+(x^2-9x+7)

  • algebra - ,

    (-8x^2-2x+4)+(x^2-9x+7)=
    -8x^2+x^2 -2.4x+(-9x) +4+7=
    -7x^2 -2.4x-9x +11=

    -7x^2 -11.4x +11

  • algebra - ,

    (-8x^2-2x+4)+(x^2-9x+7)
    to add, we just combine the numerical coefficients (or the numbers before the variable) of the same variables (meaning same letters and same exponents).
    thus,
    (-8x^2 - 2x + 4 ) + ( x^2 - 9x + 7 )
    -7x^2 - 11x + 11

    hope this helps~ :)
