Question

Solve x2 – 8x = 3 by completing the square. Which is the solution set of the equation?

-
O {4 - V19, 4 + (19)
O {4 - 11, 4 + 11}
O {4 - V8, 4 + V8}
O {4 - V3, 4 + 731

Which one

Answer 1

Answer: {4 - V19, 4 + (19)

Explanation:

(x)^2-2(x)(4)+(4)^2=(3)+(4)^2

(x+4)^2=3+16

(x-4)^2=19

taking under root

x-4=
`\sqrt{19\\`

x=4±
`√(19)`
