Answer:
Step-by-step explanation:
The Pythagorean Theorem says that a^2 + b^2 = c^2 where a and b are the two legs.
In this care leg 1 is 4 and leg two is the square root of 50. So we will square them to find c which is the hypotenuse.
4^2 + = C^2
16 + 50 = c^2
66 = c^2
c =

Step-by-step explanation:
Given
x² - 9x + 4 = 0 ( subtract 4 from both sides )
x² - 9x = - 4
Using the method of completing the square
Add ( half the coefficient of the x- term )² to both sides
x² +2 (- )x +
= - 4 +
(x - )² =
Take the square root of both sides
x - = ±
= ±
Add to both sides
x = ±
← exact solutions
