Answer:
x=-2,x=-7
Step-by-step explanation:
quadratic equation form ax^2+bx+c=0
Answer:
- 9
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 ) , then
the sum of the roots = [tex]\frac{-b}{a}[/tex]
x² + 9x + 14 = 0 ← is in standard form
with a = 1 and b = 9 , thus
sum of roots = [tex]\frac{-9}{1}[/tex] = - 9
