Chapter 10: Q12. (page 603)

Solve the equation.
$6 x^{2} - 5 x - 4 = 0$

Short Answer

Expert verified

The solutions of the given equation are $x = \frac{4}{3}, - \frac{1}{2}$ .

Step by step solution

Step 1. Define an equation.

In mathematics, an equation is a statement that asserts the equality of two expressions, which are connected by the equal sign $" = "$ .

Step 2. Write the standard form of a quadratic equation.

The standard form of a quadratic equation is given by

$a x^{2} + b x + c = 0$ , where $a \neq 0$

Step 3. Solve the equation 6x2−5x−4=0.

$6 x^{2} - 5 x - 4 = 0 6 x^{2} - 8 x + 3 x - 4 = 0 2 x (3 x - 4) + 1 (3 x - 4) = 0 (3 x - 4) (2 x + 1) = 0$

$3 x - 4 = 0$ or $2 x + 1 = 0$

$3 x = 4$ or $2 x = - 1$

$x = \frac{4}{3}$ or $x = - \frac{1}{2}$

$x = \frac{4}{3}, - \frac{1}{2}$

Therefore the solutions of the given equation are $x = \frac{4}{3}, - \frac{1}{2}$ .
