Question

im really confused and tired can someone help me?Estimate the roots of the equation by graphing. Round to the nearest tenth and write in set form, such as {-1.2,3.4}.
x2 - 6= 0

Answer 1

how do i solve that?

Answer 2

add 6 to both sides, take the square root.

Answer 3

x^2=6?

Answer 4

Yes, now what are the square roots of 6?

Answer 5

2.44948974278

Answer 6

Now round to the nearest tenth

Answer 7

2.4

Answer 8

Note that there is a negative sqrt too.

Answer 9

An equation of the form
x^2 = a, a > 0
has two roots:
x = sqrt(b) and x = -sqrt(b)

Since you have x^2 = 6, just find the square root of 6.
Then one root is the positive square root of 6 and the other root is the negative square root of 6.
