If x = 6 is a root of the quadratic equation 3x2−mx−24=0, then the value of m is __
Since, x = 6 is a root of 3x2−mx−24=0
⇒ 3(6)2–m×6−24=0
⇒ 108 - 6m - 24 = 0,
⇒ m = 14.
If x = 6 is a zero of quadratic polynomial 3x2–mx−24, then the value of m is __
Find the value of m so that the quadratic equation mx(5x−6)+9=0 has two equal roots.
