Question

If x+1



= 9 then find the value of x2 +1 2andx3+ 13​

Answer 1

Step-by-step explanation:

if x+1=9

x=8

x2+12=(8)2 +12=64+12=76

x3+13=(8)3+13=512+13=525.

Answer 2

Step-by-step explanation:

factor x +1 =9

it's zero is x=8

putting x= 8

in eq. x² + 12

p(8)=> 8²+12=0

so first of its zero is -76

putting x= 8

in eq. x³ + 13

p(8)=> 8³ + 13=0

so second zero is - 525
