we have our equation as 3x^2 +4 +7x +8 =0
which can me classified as 3x^2 + 7x +12 =0
we have to check weather -2 is a zero of this polynomial or not ....so it can only be a zero if its value in equation turns the equation a zerp so lets try
3 ( -2*-2) + 7(-2) +12
3× 4 -14 + 12
= 24 -14
=10 hence -2 is not a zero since it could not turn the polynomial into a zero
please mark the answer as brainalist
