Question

(Picture) MULTIPLYING POLYNOMIALS AND SIMPLIFYING EXPRESSIONS PLEASE HELP!!!!

Answer 1

Options (1),(3),(4) are correct and Options (2) and (5) are incorrect.

Explanation:

`3x(x-12x)+3x^(2)-2(x-2)^(2)`

`=3x(x-12x)+3x^(2)-2(x^(2)-4x+4)`
`=3x^(2)-36x^(2)+3x^(2)-2x^(2)+8x-8`
`=[tex]-32x^(2)+8x-8`

In this question we do the the simplification of term -2(x-2)^2 by squaring (x-2) then we find simplified product is not a binomial.

After multiplying, the like terms are combined by adding and subtracting.

The parentheses are eliminated through multiplication and then

The final simplified product is
`-32x^(2)+8x-8`

Therefore Options (1),(3),(4) are correct and Options (2) and (5) are not correct.

Answer 2

• -32x² +8x -8
• See below about the process

Explanation:

The simplified expression is ...

3x(x -12x) +3x² -2(x -2)²

= 3x(-11x) +3x² -2(x² -4x +4) . . . . . simplify contents of parentheses

= -33x² +3x² -2x² +8x -8 . . . . . . . .eliminate parentheses

= (-33 +3 -2)x² +8x -8 . . . . . . . . . . group the coefficients of like terms

= -32x² +8x -8
