Question

3x^-5x+p=0 the value of discriminant is 49 then value of p is​

Answer 1

Answer:

Ok good question

Step-by-step explanation:

$Given equation is 3x2−5x+p=0</p><p></p><p>Comparing with standard quadratic equation ax2+bx+c=0 we have</p><p></p><p>a=3,b=−5,c=p</p><p></p><p>Discriminant of the quadratic equation 3x2−5x+p=0 is D=b2−4ac=(−5)2−4⋅3⋅p</p><p>For the roots to be real and unequal , Discriminant should be greater than zero</p><p>∴52−4⋅3⋅p>0</p><p>⇒25>12p⇒1225>p⇒p<1225</p><p>So option B is correct.</p><p></p><p>$
