Question

Solve. 6x² + 1 = 20 Round to the nearest hundredth. Enter your answers in the boxes. The solutions are approximately ___and___.

Answer 1

Answer: 1.78 and -1.78

Step-by-step explanation:

1. You have the following equation given in the problem above:

$6x^{2}+1=20$

2. To solve it you must:

- Subtract 1 from both side of the equation:

$6x^{2}+1-1=20-1$

$6x^{2}=19$

- Divide both sides of the equation by 6, then:

$\frac{6x^{2}}{6}=\frac{19}{6}\\\\x^{2}=\frac{19}{6}$

- Apply the square root at both sides of the equation:

$\sqrt{x^{2} }=\sqrt{\frac{19}{6}}$

Then, the solution is:

$x=1.78\\x=-1.78$
