Answer 2

The correct answer is option (c) a.

• Since it is given that (x-a) is one of the factors of ax²+bx+c, which means that the value of x will satisfy the equation.
• The value of x will be (x-a) = 0, x = a. So, the value of x = a will satisfy the equation.
• Therefore, the root of the equation ax²+bx+c = 0 will be x = a as (x-a) is one of the factors of the polynomial ax²+bx+c.
