Question

If 8 is a zero of the polynomial p(x)=x2-7x-8,then find the other zero.

Answer 1

Answer:

The other zero is -1

Step-by-step explanation:

x²- 7x - 8

=(-1)² - 7(-1) - 8

=1+7-8

=8-8

=0

hence proved

Answer 2

Answer:

-1

Step-by-step explanation:

split the expression

x²-7x-8

x²-8x+x-8

x(x-8)+1(x-8)

(x-8)(x+1)

now equating to 0

(x-8)=0

x= 8

(x+1)=0

x= -1

Hence other zero is -1
