Answer:
p=4
Step-by-step explanation:
plug x=-1 into the polynomial with the unknown
(-1)³+p(-1)+(-1)+6=0
-1-p-1+6=0
-p+4=0
p=4
Answer:
x= -6 twice
Step-by-step explanation:
x^2-3x-10/x^2+12x+36
By using undefined fraction we only take the denominator and equate it to 0
x^2+12x+36=0
x^2+6x+6x+36=0
(x^2+6x)+(6x+36)=0
x(x+6)+6(x+6)=0
(x+6)(x+6)=0
x+6=0 or x+6=0
x= -6 or x= -6
therefore x= -6 twice
I would say screw it and use the calculator anyway
