Answer
x= -7, -1
Step-by-step explanation:
x^2= -7x- 8
x^2+ 7x+ 8 =0
x+7=0 x+1=0
x=-7 x=-1
Answer:
The answer is the fourth option.
Step-by-step explanation:
You start by converting the equation into standard form, resulting in x2+7x+8. You would then use the coefficients and plug them into the quadratic formula, [-(7)+√7(7)-4(1)(8)]/2 and [-(7)-√7(7)-4(1)(8)]/2. Simplified, this would become (-7+√49-32)/2 and (-7-√49-32)/2. After adding the numbers in the square root, you are left with (-7+√17)/2 and (-7-√17)/2
