For which equation does it make the most sense to solve by using the zero product property?

x² + 11x +30 = 0

4x2−2=15

x² + 2x = 119

2x2+2x−9=0

Option 1 x² + 11x +30 = 0  is correct.

Step-by-step explanation:

Zero product property states that if ab=0 then a=0 and b =0

The equation 1 can be factored easily i.e,

x² + 11x +30 = 0

x² + 5x+6x +30 = 0

x(x+5)+6(x+5)=0

(x+6)(x+5)=0

so, applying zero product property

(x+6)=0 and (x+5)=0

x=-6 and x=-5

The rest of the options 2,3 and 4  are prime equations, and they could be solved using quadratic formula or by completing the square but not using zero product property.

So, Option 1 is correct.
