Step-by-step explanation:
Use the quadratic formula

x=\frac{-{\color{#e8710a}{b}} \pm \sqrt{{\color{#e8710a}{b}}^{2}-4{\color{#c92786}{a}}{\color{#129eaf}{c}}}}{2{\color{#c92786}{a}}}
x=2a−b±b2−4ac
Once in standard form, identify a, b and c from the original equation and plug them into the quadratic formula.

<span>A Stem and Leaf Plot is a special table where each data value is
split into a "stem" (the first digit or digits) and a "leaf" (usually
the last digit).
</span>Since the key says 4|0= 40 the answer to your question is 12. Twelve cleaners have more than 80 ingredients.
Hope this helps :)
