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 Answer Hope it will help you...

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
