How would you solve 2x^2+4x+2? i'm confused!

You can start by factoring out a 2 to simplify the expression.  It would read:

Continue by dividing both sides by 2 so that it is just =0.

Now, to solve this you need to factor the expression.  This can be done by finding two numbers that when multiplied equal the c term of the equation (1) and when added equal the b term (2).  In this question, these numbers are 1 and 1.

1*1=1

1+1=2

The factored equation looks like

(x+1)(x+1)=0

Now, you can set each term equal to 0 and solve for x.  They both equal 1.

x=1

Hope this helps!!

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14
