Answer 2

Answer:

Explanation:

let quadratic equation be : ax²-bx+c=0

α + β = 2 + 5 = 7

so, b = 7

α × β = 2 × 5 = 10

so, c = 10

comparing with ax²-bx+c=0

if, a = 1 , b = 7 , c = 10

so, quadratic equation = x²-7x+10=0p

OR ,x²-(α + β)x + α x β =0

x²-(2 + 5)x + 2 x 5 =0

α=2 β=5 = x² - 7x + 10 = 0
