Introduction

In algebra, a quadratic equation is a polynomial equation of degree two, which means the highest power of the variable is two. The general form of a quadratic equation is ${ax^2 + bx + c = 0}$ , where ${a}$ , ${b}$ , and ${c}$ are constants. The roots of a quadratic equation are the values of ${x}$ that satisfy the equation. In this article, we will explore the roots of a quadratic equation given by ${x = \frac{-3 \pm \sqrt{-7m+3}}{4}}$ and determine the value(s) of ${m}$ for which this equation will have two equal roots and non-real roots.

The Nature of the Roots

The nature of the roots of a quadratic equation depends on the discriminant, which is the expression under the square root in the quadratic formula. The quadratic formula is given by ${x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}}$ . In our case, the quadratic formula is ${x = \frac{-3 \pm \sqrt{-7m+3}}{4}}$ . The discriminant is ${-7m+3}$ .

Two Equal Roots

For a quadratic equation to have two equal roots, the discriminant must be equal to zero. This is because the square root of zero is zero, and when the square root is zero, the two roots are equal. Therefore, we set the discriminant equal to zero and solve for ${m}$ .

${-7m+3 = 0}$

Solving for ${m}$ , we get:

${m = \frac{3}{7}}$

This is the value of ${m}$ for which the quadratic equation will have two equal roots.

Non-Real Roots

For a quadratic equation to have non-real roots, the discriminant must be less than zero. This is because the square root of a negative number is a complex number, and when the square root is a complex number, the roots are non-real. Therefore, we set the discriminant less than zero and solve for ${m}$ .

${-7m+3 < 0}$

Solving for ${m}$ , we get:

${m > \frac{3}{7}}$

This is the range of values of ${m}$ for which the quadratic equation will have non-real roots.
