Step-by-step explanation:

l=\frac{-{\color{#e8710a}{b}} \pm \sqrt{{\color{#e8710a}{b}}^{2}-4{\color{#c92786}{a}}{\color{#129eaf}{c}}}}{2{\color{#c92786}{a}}}

l=2a−b±b2−4ac​​

Once in standard form, identify a, b and c from the original equation and plug them into the quadratic formula.

l^{2}+9l+14=0

l2+9l+14=0

=

1

a={\color{#c92786}{1}}

a=1

=

9

b={\color{#e8710a}{9}}

b=9

c={\color{#129eaf}{14}}

c=14

Step 4:

Rearrange and isolate the variable to find each solution
