If the ratio of the two roots of the quadratic equation AX square + BX + a = 0 (a is not equal to 0) is 2:3, then the relationship between a, B and C is?

Let two be x1, X2, then X1 / x2 = 2 / 3, that is, X1 = (2 / 3) x2. According to the relationship between the root of quadratic equation of one variable and the coefficient, there are X1 + x2 = - B / A, X1 * x2 = C / A. substituting X1 = (2 / 3) x2 into the latter two expressions, there are: x2 = - 3B / (5a), (x2) ^ 2 = 3C / (2a), so 3C / (2a) = (- 3B / 5A) ^ 2, sorting out, we get that 2B ^ 2 = 25ac is the solution

In the triangle ABC, if the angle c is equal to 0 degrees, then the value range of a + B of C is 0

The solution is C = 90 ° i.e. a + B = 90 ° so a = csina, B = csinb = ccosa so (a + b) / C = (csina + ccosa) / C = Sina + cosa = √ 2Sin (a + π / 4) from a to (0, π / 2) i.e. a + π / 4 to (π / 4,3 π / 4) i.e. √ 2 / 2 ＜ sin (a + π / 4) ≤ 1 i.e. 1 ＜√ 2Sin (a + π / 4) ＜ 2 i.e. 1 ＜ (a + b)
