ANSWER

2x² + 7x + 5

EXPLANATION

This is a quadratic function, because it has two 'x' multiplying in different terms.

The standard form of a quadratic function is:

ax^2+bx+c

To transform this expression in standard form we have to apply the distributive property to multiply the terms in the parenthesis:

So for this expression a = 2, b = 7 and c = 5.

3(x-2)+2(x+1)=-14<br> plz show work
Rom4ik [11]
Hello!

First, let's write the problem.
3\left(x-2\right)+2\left(x+1\right)=-14
Apply the distributive property on the left side of the equation.
=3x-6+2x+2
Add like terms.
=5x-4
Let's plug that in into the original equation.
5x-4=-14
Add 4 to both sides.
5x-4+4=-14+4
5x=-10
Divide both sides by 5.
\frac{5x}{5}=\frac{-10}{5}

Our final answer would be,
x=-2

You can feel free to let me know if you have any questions regarding this!
Thanks!
