(x2 + 2x + 3)-(-4x2 + 5x + 6)
Simplify the 2 after the x is square

5x2−3x−3

Step-by-step explanation:

Let's simplify step-by-step.

x2+2x+3−(−4x2+5x+6)

Distribute the Negative Sign:

=x2+2x+3+−1(−4x2+5x+6)

=x2+2x+3+−1(−4x2)+−1(5x)+(−1)(6)

=x2+2x+3+4x2+−5x+−6

Combine Like Terms:

=x2+2x+3+4x2+−5x+−6

=(x2+4x2)+(2x+−5x)+(3+−6)

=5x2+−3x+−3

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
