Question

Find the value of a if, 2x⁴-ax³+4x²-x+2 I'd divisible by (2x+1). Please give correct answer only.

Answer 1

Answer:

a = - 25

Step-by-step explanation:

Answer 2

Step-by-step explanation:

let f (x) = 2x^4 - ax^3 + 4x^2 - x + 2

so it is given that f (x) is divisible by (2x + 1) that means the remainder is 0.

2x + 1 = 0

x = -1/2

putting this value of x in the f (x)

2 (-1/2)^4 - a (-1/2)^3 + 4 (-1/2)^2 - (-1/2) + 2 = 0

1/8 + 1/8a + 1 + 1/2 + 2 = 0

after solving we get,

a = -29

Hope it helps . have a good day
