Question

The roots of the equation $a + b - 4 = 0$=0 are.

• A. 1, 2
• B. 0, 2
• C. 0, 1
• D. 1, 3

Answer 1

Answer: (B)

0, 2

Answer 2

Given equation is $x$ can be written as $\frac{(x - a)(x - b)}{(x - c)}$

Let $a > c < b$, then it reduces to the equation

$x$

Now $\frac{x^{2} - 3x + 4}{x^{2} + 3x + 4}$

And $5,\frac{1}{5}7,\frac{1}{7}$.

Hence roots are 0, 2.
