Question

Solve this equation?
${x}^{2} + 6x + 8 = 0$

Answer 1

Here you go! lol 2 solutions
x1 = -1
x2 = -2

Answer 2

You can solve this equation by factoring.  To factor a quadratic, you need to find two numbers whose product is equal to the c term of the function (in this case-8) and whose sum is equal to the b term (6).  In this equation, the factors are 4 and 2 because:

4x2=8

4+2=6

The factored form of this equation is : (x+4)(x+2)=0

Now, you can solve for x by setting each term equal to 0.

x+4=0

x=-4

--------------------------------------------------------------------------------------------------------------

x+2=0

x=-2

A trick for this is to just flip the sign of the the number in the parentheses.

x={-4, -2}

Hope this helps!!
