Answer:
x^2+2x+2
Step-by-step explanation:
to find b in the equation :
b^2<4ac when having two complex roots
the required equation is x2 - Sx + P = 0
the sum of the roots :-1-i+-1-i=-2
the product=2
so the equation: x^2-(-2)x+2
x^2+2x+2
Answer:
<h2>x² + 2x + 2 = 0</h2>
Step-by-step explanation:
Formula for finding a quadratic equation when its roots are given is
x² - ( sum of roots)x + product of roots=0
The roots are
- 1 + i
- 1 - i
Sum of roots is = - 1 + i - 1 - i = -2
Product of roots is = ( -1 + i)(- 1 - i)
= 1 + 1 = 2
So the quadratic equation is
x² - (-2)x + 2 = 0
<h3>x² + 2x + 2 = 0</h3>

Answer:
y = 2x + 10
Step-by-step explanation:
Find the slope:
12 - 2 / 1 - (-4)
10 / 5 = 2
Write in point-slope form:
y - 12 = 2(x - 1)
rearrange:
y - 12 = 2x - 2
y = 2x + 10
