Question

top 10 photos of the polynomial x⁴-17x²-36x-20, if two of its zeros are +5 and -2


give the correct answer idiots.... don't write anything.. I m giving you warning​

Answer 1

Explanation:

zeroes

x=5

(x-5) is a factor

x=-2

(x+2) is a factor

(x-5) (x+2). using the formula (x+a) (x+b)

x²+2x-5x-10

=x²-3x-10

now divide the polynomial with x²-3x-10 you get the answer x²+3x+2

now factorise the quotient

you get (x+1) (x+2)

therefore,-1 and -2 are the remaining zeroes

Answer 2
