Question

4x(2x-5y+z)-3x(x+y-2)​

Answer 1

Answer: =5x2−23xy+4xz+6x

Step by Step explanation :-

4x(2x−5y+z)−3x(x+y−2)

Distribute:

=(4x)(2x)+(4x)(−5y)+(4x)(z)+−3x2+−3xy+6x

=8x2+−20xy+4xz+−3x2+−3xy+6x

Combine Like Terms:

=8x2+−20xy+4xz+−3x2+−3xy+6x

=(8x2+−3x2)+(−20xy+−3xy)+(4xz)+(6x)

=5x2+−23xy+4xz+6x
