Question 662617: Hello, I am a year 10 student and need help with the following solution:
Can you please help me with this solution:
2x²+10x+12=0
This is what I tried:
I divided the 10 and the 12 by the 2 that is shown at the start of the equation and i moved the x² of that 2 into the bracket. It looked liked this:
2(x+5x+6)=0
The 5x was from the 10, i divided the 10 by 2 and then i divided the 12 by 2 and i got 6.
I am unaware if i got this first step correct, if so can you please help me with the rest and if not can you please help me with the whole question.
Kind regards Holly, thank-you.

You can put this solution on YOUR website! Starting with
2x^2 + 10x + 12 =0
Factor out the 2
2(x^2 + 5x + 6) = 0
2(x+ )(x+ )both addition signs due to positive 5 and positive 6
consider multiple of 6 which will add up to 5
2(x+3)(x+2)=0
divide both sides by 2
(x+3)(x+2)=0
x+3=0, so x=-3
x+2=0, so x=-2
.................
Delighted to help.
