Question

m' का वह मान जिसके लिए (4x2 -6x-m); (x-3) से पूर्णतया विभाजित हो,
(a) 18
(b) 45
(c) 20
(d) 36

Answer 1

Step-by-step explanation:

Give the value of m for which (4x2 -6x-m); is exactly divisible by (x-3),

• So the given equation is 4x^2 – 6x – m
• Let f(x) = 4x^2 – 6x – m
• So to be completely divisible by x – 3 then f(3) = 0
• So putting x = 3 in the equation we get
•     f(3) = 4(3)^2 – 6(3) – m
•              = 4(9) – 18 – m
•              = 36 – 18 – m
•               = 18 – m
• Now if f(3) = 0, we get
•            18 – m = 0
•             Or m = 18
