If the roots of the quadratic equation (a²+b²) x² - 2(ac + bd)x + (c² + d²) are equal then prove that a/b = c/d

Answers

Answered by RishabhRDX

Roots of quadratic equation is equal, so,

${b}^{2} = 4ac$
Put the value of a, b and c in the formula and prove a/b=c/d...
OK... OK... I will do it...

RishabhRDX: see... D = b2-4ac... we calculate D for checking the nature of roots

RishabhRDX: if D<0... roots are imaginary

LaibaUK: Hmm ryt...thnk u

RishabhRDX: if D>0... roots are real and unequal

RishabhRDX: here Roots were equal so D = b2-4ac

RishabhRDX: that means D is 0

RishabhRDX: b2-4ac =0

RishabhRDX: b2=4ac
