How do i solve 3x² - 8x + 2 = 0 using quadratic formula?

Answers

Answer 1

Answer: $3x^2 - 8x + 2 = 0\n \na=3 , \ \ b=-8 , \ \ c=2 \n \nx_(1)=(-b-√(b^2-4ac))/(2a) =(8-√( (-8)^2-4 \cdot 3\cdot 2))/(2 \cdot 3) =(8-√( 64-24 ))/(6) =\n \n =(8-√(40 ))/(6) = ( 8-√(4\cdot 10 ) )/(6) = ( 8-2√( 10 ))/(6) = (2 (4-√( 10 )))/(6) = ( 4-√( 10 ) )/(3)$

$x_(2)=(-b+√(b^2-4ac))/(2a) =(8+√( (-8)^2-4 \cdot 3\cdot 2))/(2 \cdot 3) = ( 4+√( 10 ) )/(3)$

Answer 2

Answer:

$x = (-b +/- √(b^2 - 4ac))/(2a)$

$x = (-(-8) +/- √((-8)^2 - 4(3)(2)))/(2(3))$

$x = (8 +/- √(64 - 24))/(6)$

$x = (8 +/- √(40))/(6)$

$x = (8 +/- 6.31)/(6)$

$x = (14.32)/(6)$ x ≈ 2.39

$x = (1.68)/(6)$ x ≈ 0.28

What is 108 square root to the nearest tenth

Answers

The 108 square root value to the nearest tenth is approximately 10.4

What is 108 square root to the nearest tenth?

The square root of a number represents a value that, when multiplied by itself, results in the original number. In this case, we're looking for the square root of 108. We can use various methods such as long division, approximation techniques, or calculators to find this value.

When we calculate the square root of 108, we get a value of approximately 10.392304845413264.

However, since we are asked to round to the nearest tenth, the value becomes 10.4.

This means that when you square 10.4 (10.4 * 10.4), you get approximately 108.16, which is close to the original value of 108.
