Question

(2) One of the roots of a quadratic equation is 4 - √7. Find the equation,​

Answer 1

Answer:

One of the other root is =4−7

⇒ the other root will be =4+7(because roots are in pairs)

Sum of the roots=4−7+4+7=8

Product of the roots=(4−7)(4+7)=16−7=9

Equation will be

x2−(Sum of the roots)x+(product of roots)=0

⇒x2−8x+9=0 is the required equation.
