What is the nature of the roots of the equation \(6x^2+7x-3=0\)?

Answer and explanation

Correct answer: Two real, rational and distinct roots

Here, \(a=6\), \(b=7\), and \(c=-3\). Therefore, the discriminant is \(D=b^2-4ac=7^2-4(6)(-3)=49+72=121\). Since \(D>0\) and 121 is a perfect square, the roots are real, rational, and distinct. Option B is incorrect because irrational roots occur when \(D>0\) but is not a perfect square. Exam tip: First check the sign of the discriminant, then check whether it is a perfect square.
