Simplify the expression:
10+-2f^2+-6+7+-2f^2+-9f

30 determine the coefficient on x 12 y 24 x12y24 in ( x 3 + 2 x y 2 + y + 3 ) 18 . (x3+2xy2+y+3)18. (be careful, as x x and y y now appear in multiple terms! )

Will give brainliest summations with algebraic expressions image shown

The multiplication property of zero states that the product of any number and 0 is 0. what must be true about either a or b to make ab=0
