Question

PLEASE HELPP MEEE I HAVE 2 DAYS TO FINISH THIS CLASS AND ANOTHER

Answer 1

`x = 4± √(11 + y)`or
`x =4 ± √(11)`

Explanation:

Hint:

• Quadratic formula :

`\frac{ - b± \sqrt{ {b}^(2) - 4(ac)} }{2a}`

Simplify :

`y = {x}^(2) - 8x + 5`

`{x}^(2) - 8x + 5 = y`

`{x}^(2) - 8x + 5 - y = 0`

`\frac{8± \sqrt{( { - 8}^(2)) - 4 * (1(5 - y) } }{2 * 1}`

`x = (8±2 √(11 + y) )/(2 * 1)`

`x = 4± √(11 + y)`

The final answer is the combination of both solutions.

`x = 4 + √(11 + y)`

`x = 4 - √(11 - y)`

Hope it is helpful....

Answer 2

Explanation:

y=x²-8x+5

0=x²-2(x)(4) +4² -4² +5

11=(x-4)²

x=4±✓11
