Answer:
x=-0.544727
x=2.294727
Step-by-step explanation:
Given quadratic equation to solve:
To solve, use the quadratic formula
x= -b ± b² - 4ac / 2a
Substitute your values for a, b, & c and solve
x= -7 ± 7² - 4·(-4)·5 / 2·(-4)
x= -7 ± 49 - -80/-8
x= -7 ± 129/-8
Then, reduce the problem
x= -7/-8 ± 129/-8
x=-0.544727
x=2.294727
Answer:
do 10 20 20 40 50
Step-by-step explanation:
hope it helps sorry if it does not if not then try 1 2 3 4 5
(f+g)(x) = f(x) + g(x) = x + 11 + 3x^2
(f+g)(5) = f(5) + g(5) = 5 + 11 +3(5^2) = 91
