Which of the following is the correct factored form for the given equation? 2x^2+8x+6=0

3241004551 [841]

It would be 2(x+3)(x+1)=0

Explanation:
I used factor by grouping. You multiply the first term (2) by the last term (6). This gives you 12 then take the factors of 12 that add up to the middle term 8. You get 6 and 2.
It should look like 2x^2+6x+2x+6=0
when you do factor by grouping you factor the first two terms and then the last two terms separately. So you get (2x+2) and (x+3). (2x+2) could be factored into 2(x+1). Then you put everything together and get 2(x+3)(x+1)=0

An artist wants to frame a square painting with an area of 400 square inches. She wants to know the length of the wood trim that

marysya [2.9K]

Area of square painting is 400 square inches.

Let the side of square painting is = a inch

So the area of square painting is = $a^2$ square inch.

So $a^2 = 400

a = \sqrt{400}$

$a = 20 inch$

Length of wood trim to need to go around the painting is equal to the perimeter of square painting .

So the perimeter of square painting is = 4 * (side)
= 4* 20 = 80 inch.

So the required length of wood trim is = 80 inch.
