If 5x2 - 2x + a is divided by (x-2) , the remainder is 7 , find 'a'

1.	If 5x2 - 2x + a is divided by (x-2) , the remainder is 7 , find 'a'
Answer» ong>ANSWER: x-2 = 0 x = 2 f(x) = a - 2X + 5x^2 f(2) = a - 2(2) + 5(2)^2 7 = a - 4 + 20 7 = a + 16 a = 7 - 16 a = -9

Answer»

ong>ANSWER:

x-2 = 0

x = 2

f(x) = a - 2X + 5x^2

f(2) = a - 2(2) + 5(2)^2

7 = a - 4 + 20

7 = a + 16

a = 7 - 16

a = -9
