Question

How do you find the product of `(-6w^2)(7w^2)`?

Answer 1

`-42w^4`

Explanation:

Write as `(-1)xx6xx7xxw^2xxw^2`

giving: `" "-42w^4`

Answer 2

`-42w^2`

Explanation:

One always has to multiply the numbers together first and then the variables --- so that means:
multiply -6 x 7 and then
multiply the variables.
In this instance, the variables have already been simplified :)
Then multiply everything together. . .

so as an example:

`= -3xx4xxa^2xxa^3 = -12a^5`
