Verified Answer :

the correct answer is
a) x=-8/3,-2

Answer:

Given the equation: \(3x^2+14x+16=0\)

The general equation of quadratic formula for \(ax^2+bx+c=0\) where a, b and c are constant;


then, the solution for this equation  is given by;

\(x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\)              ......[1]

From the equation, \(3x^2+14x+16=0\) we have

a =2, b=14 and c=16

Substitute these values in [1] to solve for x;

\(x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}=\frac{-14\pm\sqrt{(14)^2-4(3)(16)}}{2(3)}\)              

or

\(x=\frac{-14\pm\sqrt{196-192}}{6} =\frac{-14\pm\sqrt{4}}{6}\)

Simplify:

\(x=\frac{-14\pm\sqrt{4}}{6} =\frac{-14\pm 2}{6}\)

then,

\(x=\frac{-14+2}{6} =\frac{-12}{6} =-2\) and

\(x=\frac{-14-2}{6} =\frac{-16}{6} =\frac{-8}{3}\)

Therefore, the solutions for the given equation is; x =-2 and \(x =-\frac{8}{3}\)
