Question

−7(−6m2+8m)−4m2+6m упростить

Answer 1

-7(-6m²+8m)-4m²+6m=42m²-56m-4m²+6m=38m²-50m

Answer 2

To simplify the expression, let's start by distributing the negative sign outside the parentheses:

−7(−6m^2 + 8m) − 4m^2 + 6m

First, distribute the negative sign:

= 42m^2 - 56m - 4m^2 + 6m

Now, combine like terms:

= (42m^2 - 4m^2) + (-56m + 6m)

= 38m^2 - 50m

So, the simplified expression is 38m^2 - 50m.
