Question

x^3-3x^2-9x-5 factories​

Answer 1

Step-by-step explanation:

the factors of -5 is +-1,+-5

lte the p(x) be 5

p(5)=5^3-3(5)^2-9(5)-5

125-75-45-5

50-45-5

so the 5 is x, x=5,x-5=0

x^3-3x^2-9x-5 ÷ x-5

divide it

then form this

(x-5)(Quotient)

Then middle split the quotient

then again form this

(x-5)(Middle splitted quotient)

this is answer
