The polar equation of $x to the power of 3 end exponent plus y to the power of 3 end exponent equals 3$ axy is

If $alpha not equal to beta comma alpha 2 equals 5 alpha minus 3 comma beta 2 times equals 5 beta minus 3 comma$ then the equation whose roots are $alpha divided by beta straight & beta divided by alpha$

Let p, q $element of$ {1, 2, 3, 4}. Then number of equation of the form px² + qx + 1 = 0, having real roots, is

Here we used the concept of quadratic equations and solved the problem. We also understood the concept of discriminant and used it in the solution to find the intervals. Therefore, total 7 seven solutions are possible so $7$ equations can be formed.

Let p, q $element of$ {1, 2, 3, 4}. Then number of equation of the form px² + qx + 1 = 0, having real roots, is

ax² + bx + c = 0 has real and distinct roots null. Further a > 0, b < 0 and c < 0, then –
