Answer:

2x^2+2x+2 or 2(x^2+x+1)

Step-by-step explanation:

C = 2x^2+5x-1

D = x-1

C-3D = (2x^2+5x-1) - 3 * (x-1) =2x^2+5x-1-3x+3 =2x^2+2x+2 = 2(x^2+x+1)

What is the simplified form of this expression (8x^2-3x+1/3) - (2x^2-8x+3/5)
irinina [24]

Answer:=6x2+5x + −4/15

Step-by-step explanation:Let's simplify step-by-step.

8x2−3x+13−(2x2−8x+3/5)

Distribute the Negative Sign:

=8x2−3x+13+−1(2x2−8x+3/5)

=8x2+−3x+13+−1(2x2)+−1(−8x)+−1(3/5)

=8x2+−3x+13+−2x2+8x+−3/5

Combine Like Terms:

=8x2+−3x+1/3+−2x2+8x+−3/5

=(8x2+−2x2)+(−3x+8x)+(1/3+−3/5)

=6x2+5x+−4/15

Evaluate this piecewise function
ohaa [14]

Answer:

f(-2) = 2 and f(0) = 0.

Step-by-step explanation:

The piece wise function is given by, f(x) = x³ for x ≠ - 2 and f(x) = |x| for x = - 2.

Now, as defined above at x = -2, f(x) = |- 2| = 2

So, f(-2) = 2

Again, at x = 0, f(x) = x³ = (0)³ = 0.

So, f(0) = 0.

Hence, f(-2) = 2 and f(0) = 0. (Answer)
