Question

Solve  $$ 2{{x}^{2}}+13x+21=0 $$


Solution

Consider given equation,


$$ 2{{x}^{2}}+13x+21=0 $$

$$ 2{{x}^{2}}+7x+6x+21=0 $$

$$ 2x\left( x+7 \right)+3\left( x+7 \right)=0 $$

$$ \left( x+7 \right)\left( 2x+3 \right)=0 $$

When, x+7=0

$$x=-7$$

When,

$$2x+3=0$$

$$x=\dfrac{-3}{2}$$


Hence, this is the answer.
