Answer:

roots of the equation[25x^2-10ax+a^2-16b^2

Step-by-step explanation:

D=b^2-4ac

D=(-10a)^2-4(25)(a^2-16b^2)

D=100a^2-100a^2+1600b^2

D=1600b^2

x=(-b+√d)/2a,(-b-√d)/2a

x={-(-10a)+√1600b^2}/2(25),{-(-10a)+√1600b^2}/2(25)

x=(10a+40b)/2,(10a-40b)/2

x=5a+20b,5a-20b

I hope this solution helps you


LakshyaSarraf18: I think in this question, we have not given equal roots... so we can't take this formula, instead we have to take this formula :- -b +- √b^2 - 4ac / 2a
LakshyaSarraf18: what do you think??
LakshyaSarraf18: and the answer will be a+4b/5 , a-4b/5
