Question

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

Answer 1

Answer:

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

Step-by-step 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

Answer 2

Answer:

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

Step-by-step 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.
