Question

obtain all zeroes of polynomial x4+7x3+7x2-35x-60,if two of its zeroes are -3 and -4.
plzzz....i need it fast

Answer 1

√5, -√5
This is the answer
Divide the dividend with divisor as;
x"2-7x+12

Answer 2

Answer:

hello,

hope my ans helps

p(x)=x^4+7x^3+7x^2-35x-60

given zeros are -3,-4 they can also be written as x+3,x+4

(x+3)(x+4)=x^2+7x+12

now we divide this with p(x)

and get a quotient x^2-5

we know (a+b)(a-b)=a^2-b^2

and x^2-5 can b written as (x-root5)(x+root5)

so the zeros are -root5 and +root 5
