Form the quadratic equation whose one root is 2 + 2^(1/2)​
Oksanka [162]

9514 1404 393

Answer:

  x^2 -4x +2 = 0

Step-by-step explanation:

The other root is the conjugate of the given one, so is 2-√2. The quadratic equation in factored form is then ...

  (x -2-√2)(x -2+√2) = 0

Expanding this, we get ...

  (x -2)^2 -(√2)^2 = 0

  x^2 -4x +4 -2 = 0

  x^2 -4x +2 = 0 . . . . the equation you're looking for

50 POINTS AGAIN<br> and I will give brainliest
Novosadov [1.4K]

Answer:

apple = 4

blackberry =5

Step-by-step explanation:

Let a = apple pie cost

b =blackberry pie cost

4a +9b = 61

7a +6b = 58

Multiply the first equation by 7

7(4a +9b) = 61*7

28a +63b = 427

Multiply the second equation by -4

-4(7a +6b) = 58*-4

-28a -24b = -232

Add these two new equations together to eliminate a

28a +63b = 427

-28a -24b = -232

-----------------------------

0a +39b =195

Divide each side by 39

39b/39 = 195/39

b= 5

Now we need to find a

4a +9b = 61

4a +9(5) = 61

4a +45 = 61

4a+45-45 =61-45

4a = 26

Divide by 4

4a/4 =16/4

a = 4
