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:
Options (1),(3),(4) are correct and Options (2) and (5) are incorrect.
Step-by-step explanation:
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
Therefore Options (1),(3),(4) are correct and Options (2) and (5) are not correct.

Given is a piecewise function which follows different expressions according the the value of input x.
Given
It says to find f(-4) i.e. the value of function f(x) at x = -4.
At point x = -4, f(x) is x³, if -5 ≤ x ≤ 2.
So, f(-4) = (-4)³
f(-4) = -4 × -4 × -4
f(-4) = -64.
Hence, option A is correct i.e. -64.
