Question

2 is zero of the polynomial of x²-3x +a find the value of a​

Answer 1

Answer:

2

Step-by-step explanation:

let the given polynomial be p(x)

Since 2 is the zero of polynomial

therefore ,

p(2)= 0

=> 2^2-3×2+a=0

=>a = 6-4 = 2

hence the value of a equals to 2

Answer 2

Let,

p(x) = x² - 3x + a

Given that: 2 is the zero of p(x).

After putting the value of the zero of a polynomial, results in 0 after evaluation.

∴ p(2) = 0

→ (2)² - 3(2) + a = 0

→ 4 - 6 + a = 0

→ - 2 + a = 0

→ a = 2

∴ The value of (a) in the given polynomial is (2).
