For your first question...
Given quadratic : ax² – 2bx + c = 0
Now, b²- ac ²- 4ac
Thus, roots are imaginary.
We have, 4a+4b+c²- 2b(-2) + c
The required expression is a + 2b + c or a(-1)² – 2b(-1) + c or f(-1)

Now understand the question by graphical method. Since the roots are imaginary, so the graph of f(x) is not going to intersect the x-axis. Also, f(-2)

Now, b2 - ac 2 - 4ac
Thus, roots are imaginary.
We have, 4a+4b+c2 → a(-2)²- 2b(-2) + c → f(-2)
The required expression is a + 2b + c or a(-1)2 – 2b(-1) + c or f(-1)

Now understand the question by graphical method. Since the roots are imaginary, so the graph of f(x) is not going to intersect the x-axis. Also, f(-2)
