Q. ℓ(x)=x4+36x2−10,000The polynomial function ℓ is defined. What is the remainder of ℓ(x) when divided by x+10 ?
Use Remainder Theorem: To find the remainder of ℓ(x) when divided by x+10, we can use the Remainder Theorem. The Remainder Theorem states that the remainder of a polynomial f(x) divided by x−k is f(k). Since we are dividing by x+10, we will find ℓ(−10).
Substitute x=−10: Substitute x=−10 into the polynomial ℓ(x).ℓ(−10)=(−10)4+36(−10)2−10,000
Calculate value of ℓ(−10): Calculate the value of ℓ(−10).ℓ(−10)=(10000)+36(100)−10,000ℓ(−10)=10000+3600−10000
Simplify expression: Simplify the expression to find the remainder.ℓ(−10)=10000+3600−10000ℓ(−10)=3600
