Question

find the value of k, if( x_a) is a factor of x×3 _ a×2x + x+ 2​

Answer 1

Answer:

3x2a+2=6a+2== 8a ans fjjfydfhcdgb

Answer 2

Answer

a = -2

Step-by-step explanation

x - a is factor of polynomial ⇒ x - a = 0 ⇒ x = a

Given Polynomial : p(x) = x³ - ax² + x + 2

• Substitute x = a in polynomial p(x)

x³ - ax² + x + 2 = 0

⇒ a³ - a(a)² + a + 2 = 0

⇒ a³ - a³ + a + 2 = 0

⇒ a + 2 = 0

⇒ a = 0 - 2

⇒ a = -2
