(x2 - y²) from (2x? - 3y2 +6xy)
Answers
Answer:
(x2 – y2) from (2x2 – 3y2 + 6xy) The difference of two like terms is a like term whose coefficient is the difference of the numerical coefficient of the two like terms. We have, = (2x2 – 3y2 + 6xy) – (x2 – y2) Change the sign of each term of the expression to be subtracted and then add. = 2x2 – 3y2 + 6xy – x2 + y2 = (2x2 – x2) + (– 3y2 + y2) + 6xy = (2 – 1)x2 + (– 3 + 1)y2 + 6xy = 1x2 + (– 2y2) + 6xy = 1x2 – 2y2 + 6xy
