Question

3x²- 33x -240 =0 solve ​

Answer 1

$\star\:\:\bf\large\underline\blue{Question:-}$

Solve the equation $3 {x}^{2} - 33x - 240 = 0$

$\star\:\:\bf\large\underline\blue{Solution:-}$

$3 {x}^{2} - 33x - 240 = 0$

$\implies \frac{3 {x}^{2} - 33x - 240}{3} = \frac{0}{3}$

$\implies {x}^{2} - 11x - 80 = 0$

$\implies {x}^{2} - 16x + 5x- 80 = 0$

$\implies x(x - 16) - 5(x - 16) = 0$

$\implies (x - 16)(x - 5) = 0$

Therefore,

$x - 16 = 0$

$\implies x = 16$

Also,

$x - 5 = 0$

$\implies x = 5$

Roots are:-

$16$

$5$
