What is the Sum of Roots of x^2+9x+14=0?

- 9

Step-by-step explanation:

Given a quadratic equation in standard form

ax² + bx + c = 0 ( a ≠ 0 ) , then

the sum of the roots =

x² + 9x + 14 = 0 ← is in standard form

with a = 1 and b = 9 , thus

sum of roots = = - 9

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
