Simplify the polynomial.

1. 4a²b + 5 - 6a³b - 3a²b + 2a³b

Answers

1.\n \n 4a^2b + 5 - 6a^3b - 3a^2b + 2a^3b = \n \n = - 6a^3b + 2a^3b +4a^2b - 3a^2b+ 5=\n \n= - 4a^3b + a^2b + 5
4a²b + 5 - 6a³b - 3a²b + 2a³b

We first simplify similar expressions,

4a²b - 3a²b + 5 -6a³b + 2a³b

= a²b + 5 - 4a³b

Which expression is equivalent to –2(5x – 0.75)?10x – 0.75

–10x + 1.5

Answers

-10x + 1.5 because you get rid of the parenthesis so -2 times 5 is -10 ( -10x ) and then -2 times -0.75 equals positive 1.5 due to two negatives canceling out to positive hope this helped!
