2x2 + 6x + 1 = 0 pls solve this quadratic equation

PolarNik [594]

Answer:

2x² + 6x + 1 = 0

Formula

$x=\frac{-b+/-\sqrt{b^{2}-4ac}}{2a}\\ \\$

a = 2

b = 6

c = 1

$x=\frac{-6+/-\sqrt{6^{2}-4*2*1}}{2*2}$

$x=\frac{-3+\sqrt{7}}{2}\\ \\x=\frac{-3-\sqrt{7}}{2}$

What is the variable equal in the equation ten less than 3 times a number is the same as the number plus 4?

klio [65]

The variable is "the number". To make it easier to write the equation
and work with it, let's call the variable 'M' for 'Mystery number'.

3 times the number is 3M .

-- 10 less than that is 3M-10 .
-- the number plus 4 is M+4 .

The question says that these two things are the same.
So ...
3M - 10 = M + 4

Subtract 'M' from each side: 2M - 10 = 4

Add 10 to each side: 2M = 14

Divide each side by 2 : M = 7
