Question

The quadratic equation whose one rational root is 3 + √2 is

(a) x² – 7x + 5 = 0

(b) x² + 7x + 6 = 0

(c) x² – 7x + 6 = 0

(d) x² – 6x + 7 = 0​

Answer 1

Answer:

d) part.

Step-by-step explanation:

When you put the value of x as 3+root2, the equation will satisfy

Answer 2

Step-by-step explanation:

There is always the only one way of solving these. the other root will be always 3-√2

Therefore, x^2-(3+√2+3-√2)x+(3+√2)(3-√2)=0

x^2-6x+7=0
