X^2 +2x +10 = 0

D = 4 -40 = - 36 

x_1,2 = (-2 +/- sqrt(-36))/2 = (-2 +/- 6i)/2 = 2(-1 +/- 3i)/2 = -1 +/- 3i 

x_1,2 = -1 +/- 3i   or more understandably 

x_1 = -1 -3i and x_2 = -1 +3i

hope this will help you

Find f(-10) f(x)=7x-5​
Inessa [10]

Answer:

<h2>f(-10) = -75</h2>

Step-by-step explanation:

F(x) is simply another way of saying y. We are given the x value of -10. We can substitute this in for x and find y.

f(-10) = 7(-10) - 5

f(-10) = -70 - 5

f(-10) = -75
