Question

Simplify and determine the coefficient of (-2/5x)(5y)(-2x).

Answer 1

Solution/Answer : 4

Solution: the first you do is multiply the last two parentheses to get -10xy


Now we are left with ( -2/5x)(-10xy)
Then we multiply that out into
(-2*-10)/5*x^2y = 20/5x^2y =
4x^2y

The coefficient in this case would be four. (In case you were confused about what a coefficient actually is, it’s the number you multiply a variable by)

Hopes this helps :)
