Answer:
x = -4, -2
Step-by-step explanation:
Key skills needed: Quadratics, Factoring, Solving for Roots
1) We are given : [tex]x^2 + 6x + 8 = 0[/tex] and we need to solve for the roots.
2) You have to factor.
You need to find what factors of 8 add up to 6.
The factors of 8 are --> 1,2,4,8
The 2 factors that add up to 6 and multiply to equal 8 are --> 2 & 4
3) This means it would become ---> [tex](x+4)(x+2) = 0[/tex].
4) Set x + 4 = 0 and get x = -4 as one root
Set x + 2 = 0 and get x = -2 as another root.
The 2 roots are -4, and -2
Hope you understood and have a nice day!! :D
