Answer:

Step-by-step explanation:

first you want to graph f(x) (use a graphing calculator to see if you don't know how to)

you can see that the minimum of f(x) is -4 when x=-8

the minimum of g(x) is 1 when x=3

Find: (4x2y3 + 2xy2 – 2y) – (–7x2y3 + 6xy2 – 2y) Place the correct coefficients in the difference.

DanielleElmas [232]

Answer: Our required answer will be

$11x^2y^3-4xy^2$

Step-by-step explanation:

Since we have given that

$(4x^y^3+2xy^2-2y)-(-7x^2y^3+6xy^2-2y)$

We need to get the difference:

1) We first open the second bracket and make appropriate change in signs :

$4x^y^3+2xy^2-2y+7x^2y^3-6xy^2+2y$

2) Gather the like terms together :

$4x^2y^3+2xy^2-2y+7x^2y^3-6xy^2+2y\\\\=4x^2y^3+7x^2y^3+2xy^2-6xy^2-2y+2y\\\\=11x^2y^3-4xy^2$

Hence, our required answer will be

$11x^2y^3-4xy^2$
