Which statements are true about the fully simplified product of (b-2c)(-3b c) ?

Mathematics

AVprozaik [17]3 years ago
7 0

Answer:

( 3 )The simplified product has a degree of 2.

Step-by-step explanation:

(b-2c)(-3b+c)

Multiply the parenthesis using FOIL method

multiply b inside the second parenthesis

b(-3b+c)= -3b^2 +bc

-2c(-3b+c)= 6bc -2c^2

(-3b^2 +bc+6bc -2c^2)

Combine like terms

-3b^2 +7bc -2c^2

Simplified product has 3 terms, and the degree of 2 because we have b^2

and c^2

Which term could be put in the blank to create a fully simplified polynomial written in standard form?
Katena32 [7]

Correct Question:

Which term could be put in the blank to create a fully simplified polynomial written in standard form?

8x^3y^2 -\ [\ \ ] + 3xy^2 - 4y3

Options

x^2y^2            x^3y^3         7xy^2         7x^0y^3

Answer:

x^2y^2

Step-by-step explanation:

Given

8x^3y^2 -\ [\ \ ] + 3xy^2 - 4y^3

Required

Fill in the missing gap

We have that:

8x^3y^2 -\ [\ \ ] + 3xy^2 - 4y^3

From the polynomial, we can see that the power of x starts from 3 and stops at 0 while the power of y is constant.

Hence, the variable of the polynomial is x

This implies that the power of x decreases by 1 in each term.

The  missing gap has to its left, a term with x to the power of 3 and to its right, a term with x to the power of 1.

This implies that the blank will be filled with a term that has its power of x to be 2

From the list of given options, only x^2y^2 can be used to complete the polynomial.

Hence, the complete polynomial is:

8x^3y^2 -x^2y^2+ 3xy^2 - 4y3
