Answer:
![x^2 - 3x -10 = 0](https://tex.z-dn.net/?f=x%5E2%20-%203x%20-10%20%3D%200)
Step-by-step explanation:
Given
Roots = -2 and 5
Required
Write the equation
We have that:
x = -2 and x = 5
Simplify further
x + 2 = 0 or x - 5 = 0
Multiply the results of the above
![(x + 2)(x - 5) = 0](https://tex.z-dn.net/?f=%28x%20%2B%202%29%28x%20-%205%29%20%3D%200)
Open brackets
![x^2 + 2x - 5x -10 = 0](https://tex.z-dn.net/?f=x%5E2%20%2B%202x%20-%205x%20-10%20%3D%200)
![x^2 - 3x -10 = 0](https://tex.z-dn.net/?f=x%5E2%20-%203x%20-10%20%3D%200)

Answer:
point C
Step-by-step explanation:
Given: z1 = 7 - 3i and Z2 = 3 – 5i
Add the numbers with numbers and i's with i's
z1: 7 - 3i
z2: 3 - 5i
z1+z2 = 10 - 8i
the x-axis is the real number and y-axis is the imaginary numbers.
point C is at the -8i and positive 10
