Question

if the sum of the roots of the equation x^2-x(1+2alpha)+alpha is zero then alpha is​

Answer 1

Answer:

Step-by-step explanation:

If the sum of squares of roots of equation x^(2)-(sin alpha-2)x-(1+sin alpha)=0 is the least, then alpha is . If the sum of squares of roots of equation x2-(sinα-2)x-(1+sinα)=0 is the least, then α is equal to  If `2 + cos^2 alpha, 2 + sin^2 alpha`.
