Answer:
2-7i is the correct option.
Step-by-step explanation:
We have been given the complex number real part 2 and imaginary part 7 it can be expressed as:
2+7i
And the conjugate means in the complex number is opposite sign of imaginary part that is in general:
a+ib will have conjugate a-ib
So, the conjugate of 2+7i is 2-7i
Hence, Option d is correct.
You can use the quadratic formula:
X = (-b +/- ✓b^2 - 4ac)/2a
You then can get:
X = 2 or 1.5
