Question

X²+2x+3 os divided by x+ then remainder is

Answer 1

Answer:

Step-by-step explanation:

we know that P(x) = q(x)×g(x)+r(x)

p(x) = f(x) = ?

q(x) = x²-2x-3

g(x) = x²-5

r(x) = 0

1 ]

f(x) = q(x)×g(x)+r(x)

f(x) = (x²-2x-3)×(x²-5)+0

f(x) = x²(x²-2x-3)-5(x²-2x-3)

f(x) = x⁴-2x³-3x²-5x²+10x+15

f(x) = x⁴-2x³-8x²+10x+15

2 ]

x⁴-2x³-8x²+10x+15 = 0

(x+√5) • (x- √5) • (x + 1) • (x - 3) = 0

so zeroes are

x = -√5

x = +√5

x = -1

x = 3
