Question

Find zero of the polynomial 15x^2+x-6

Answer 1

Given equation

$15x^{2} +x-6=0$

Solving, we get,

$15x^{2} +x-6=0$

$\implies 15x^{2} +10x-9x-6=0$

$\implies5x(3x+2)-3(3x+2)=0$

$\implies (5x-3)(3x+2)=0$

Now,

$5x-3=0$

$\implies \boxed{\boxed{\bold{x = \frac{3}{5}}}}}}}}}$

$3x+2=0$

$\implies \boxed{\boxed{\bold{x = \frac{-2}{3}}}}}}}}}$
