Question

m का वह मान ज्ञात कीजिए जिससे समीकरण 5x² – 3x + m = 0 के मूल समान होंगे।

Answer 1

Answer:

step by step explanation :

for the roots to be equal , the discriminant should be equal to 0

therefore , b^2 - 4ac = 0

here b= -3 , a = 5 & c = m

.

substituting the values in formulae

((−5)2+(4)(5)m=0

25+20m=0

20m+25=0

Step 2: Subtract 25 from both sides.

20m+25−25=0−25

20m=−25

Step 3: Divide both sides by 20.

20m

20

=

−25

20

m=

−5
