Step-by-step explanation:
*Given* :
• A village of India is suffering from flood . A group of students decide to help them with food items , cloths etc. • The students collect money which is represented by 5x4 + x³ - 3x² + ax - b . • The number of student is secretly presented by x² + 2 .
★ To find ★ :
• The values of a and b
★ Solution ★ :
Given that
Total number of students = x² + 1
The total money collected by them = 5x4 + x³ - 3x² + ax - b
To find the values of a and b we have to divide the given polynomial by x² + 1
x² + 1 ) 5x¹ + x³ − 3x² + ax - b ( 5x² + x - 8
5x^4+। 5x²
(-)
________________________________
x³-8x²+ax
(-) x³ +x
__________________________________
-8x²+(a-1)x-b
(-) -8x²। -8
___________________________________
(a-1)x-b+8
According to the given problem We have the remainder is zero
Therefore, (a-1) = 0
and -b+8 = 0 => a = 1
and b 8
*Answer *:- • The value of a = 1
The value of b = 8
