Question

If x= - 2 what is 3(2x - 4) +x^2+5​

Answer 1

Answer:

-23

Step-by-step explanation:

= 3(2x - 4) +x^2+5​

= 3(2 × {-2} - 4)+(-2)² + 5

= 3(-4 - 4) + (-4) + 5

= 3(-8) - 4 + 5

= -24 + 1

= -23

Answer 2

Answer:

the answer is -15

Step-by-step explanation:

3(2x-4)+$x^{2}$+15

x=-2

3(2(-2)-4)+(-2*2)+5

3(-4-4)+4+5

3(-8)+9

-24+9

=-15
