Question

subract
(2x to the 4th power +8x to the 3rd power -2)-( 3x to the 2nd power-7x+3) please someone help

Answer 1

this is your expression?\[2x^4+8x^3-2-(3x^2-7x+3)\]

Answer 2

distribute the -1\[=2x^4+8x^3-2-3x^2+7x-3\]commute and combine like terms (combine the -2 with the -3)\[=2x^4+8x^3-3x^2-5\]it is typical to write with descending powers

Answer 3

so then would my answer be 8x to the 9th power?

Answer 4

no, your answer would be the last algebraic line from my last post
