A quadratic equation with integral coefficient has integral roots. Justify your answer.

Open in App Solution

No, a quadratic equation with integral coefficients may or may not have integral roots.

**Justification**

Consider the equation,

8x2– 2x – 1 = 0

The roots of the given equation are

12 and -14

which are not integers.

Hence, a quadratic equation with an integral coefficient might or might not have integral roots.

Solution Verified by Toppr

Correct option is B)

The given statement is false.

A quadratic education with integral coefficient can have its roots in fraction, i.e., non-integral.

For example, 5x 2 +3x−8=0 ⇒5x 2 +8x−5x−8=0 ⇒x(5x+8)−1(5x+8=0 ⇒(5x+8)(x−1)=0 ⇒5x+8=0 or (x−1)=0

Therefore, the roots are x=

5 −8 and x = 1
