Question

find the quadratic equation whose one of the root is 2 and 5

Answer 1

x^2 -(alpha +beta) x +alpha beta=0
alpha +beta = 2+5=7
alpha beta =2×5 =10
now
x^2-(7)x +10=0
x^2-7x+10=0

Answer 2

Answer:I

Step-by-step explanation:

Alpha = 2 , beta = 5

Alpha + beta = 7

Alpha. Beta = 10

Eq = x² - (7)x +10

= x²-7x+10
