Question

25X2 - 30x+7 = 0 by using sridharacharya formula​

Answer 1

Answer:

(3+√2)/5 and (3-√2)/5

Step-by-step explanation:

25x²-30x+7 =0

By sridharacharya formula or quadratic formula

⇒ (-b±√(b²-4ac) ) ÷2a

⇒b =-30 ,a= 25 ,c=7

[-(-30)± √((-30)²-4(25)(7)) ] ÷ 2(25)

⇒[ 30 ± √{900 -700} ] ÷ 50

⇒(30 +10√2 )/5   ;(30-10√2)/5

Hence proved
