Can someone correct these for me please...
Multiply. (x+2)(x2)
My answer..x^24
Write in descendingexponent form, and give the degree
4x^5+x^87
My answer: In descendingexponent form would be: x^8+4x^57, The degree is 8
Multiply. 3xy^2(5xy4x+6y)
My answer: 13x^2y^2+18xy^3
the first two are correct, the last is not You should have three terms. The first term will be 15x^ ^{2} y^^{3 }
