Question

x -2 is a factor of x³ - 2ax² +ax - 1 , then the value of a is *​

Answer 1

Step-by-step explanation:

कॉन्टेंट·उत्तर: यदि X+2 एक कारक है, तो x= -2 दिए गए समीकरण का शून्य है

Answer 2

Answer:

a =  $\frac{7}{6}$

Step-by-step explanation:

x - 2 is a factor then

x - 2 = 0

x = 2

$2^{3} - 2a(2)^{2} +a(2) -1 = 0$

8 - 8a + 2a - 1 = 0

7 - 6a = 0

6a = 7

a = $\frac{7}{6}$
