Question

Solve 3x2+7x+1=0 using the quadratic formula.

Answer 1

Answer:

$x=\frac{-7+-\sqrt{37} }{6}$

Step-by-step explanation:

This (±) goes between the $-7$ and $\sqrt{37}$

$3x^{2} +7x+1=0$

$ax^{2} +bx+c$

$-b$ ± $\sqrt{b^2-4ac}$/2a

$-7$ ± $\sqrt{(7)^2-4(3)(1)}$/2(3)

$-7$ ± $\sqrt{49-12}$/6

$-7$ ± $\sqrt{37}/6$
