Question

23.Find the quadratic equation whose one rational root is 3 + √2 *​

Answer 1

Answer:

x²-6x+7

Step-by-step explanation:

Rational roots always occur in pairs,

One root is 3 + √2, then 2nd root will be 3 -√2

S= 3 + √2+ 3 - √2= 6

P=(3 + √2) (3 -√2) = 3²-(√2)²= 9-2=7

So, quadratic equations will be

x² -Sx+ P

x² - 6x+ 7

Answer 2

Answer:

I hope it help you.

Step-by-step explanation:

3 - √2

this is other root

k(x^2-(a+b)x-ab is formula

x2-(3+2^1/2+3-2^1/2)x+(3)^2-(2^1/2)^2

x^2-6x+(9-2)

x^2-6x+7

this is quadratic equation
