Answer 1

Answer:

22 /4 = a

Step-by-step explanation:

Question:-

f(x)=x* - 2x +3x^2 - ax +3a - 7, when divided by x +1 leaves a remainder 19. Find value of a??

Solution :-

x+1 = 0

x = - 1

According to question :-

f(-1) = 3(-1)^2 -2(-1) + (-1) - 7 +3a - a(-1)

19 = 3 + 2 - 1 - 7 +3a + a

19 = 5 - 8 +4a

19 = - 3 + 4a

19 + 3 = 4a

22 /4 = a
