Answer:
If a = 3
a -7 = -4
Step-by-step explanation:
Here, we want to find the value of a -7 given that a = 3
To find this value, we are going to make a substitution
We simply substitute 3 for the value of a
we have this as;
3 -7 = -4
4. If the determinant delta of a quadratic equation is positive, the equation has two real roots. If the determinant is negative, it has two imaginary roots. In this case, delta=b^2-4ac=(-1)^2-4*1*4=-15. Therefore, this equation has two imaginary roots.
