Question

What are the approximate solutions of 4x^2 + 3 = -12x to the nearest hundredth?

Answer 1

well rewriting the equation you have

\[4x^2 + 12x + 3 = 0\]

now use the general quadratic formula

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

where a = 4, b = 12 and c = 3

and solve for x

Answer 2

then when you get your answers, round to 2 decimal places.
