Question

if x² +ax²-bx-13 has × as factors ​

Answer 1

Answer:

210 is the coreect answer

Answer 2

Answer:

a=12 and b=0 is the correct answer plz mark me as brilianist

Step-by-step explanation:

p(x)=x-1

x-1=0

x=1

p(1)=(1)²+a(1)²-b(1)-13

=1+a-b-13

a-b-12

a-b=12__equation no.1

taking fron equation no.1,we get

a=12-b___equation no.2

substitutig the value of a=12-b in equation_no.1,

(12-b)-b=12

12-2b=12

-2b=12-12

b=0/2

b=0

substituting the value of b=0 in equation_no.2

a=12-(0)

a=12

answer:-a=12 and b=0
