Answer:
x = 4 ±
Step-by-step explanation:
Given
x² - 8x + 3 = 0 ( subtract 3 from both sides )
x² - 8x = - 3
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 4)x + 16 = - 3 + 16
(x - 4)² = 13 ( take the square root of both sides )
x - 4 = ± ( add 4 to both sides )
x = 4 ±

Hi there! The answer is 10.
We can use PEMDAS (Parenthesis, exponents, multiply, divide, add, subtract) to find our answer.
Since we cannot work inside the parenthesis in this question and since we don't have exponents, we can move on to multiplying.
Our next step would be subtracting. To make the process of subtracting some easier, I'll first change the fraction into a decimal.
Finally subtract.
The answer is 10.
