Question

. If A=x2-7x+10 and B=x-2, find the expression representing A÷B.
a) (x+5) b) (x-5)
write it step by step.

Answer 1

Answer:

Step-by-step explanation:

(x)=

x

2

−7x+10

x

2

−bx+25

​

=

(x−2)(x−5)

x

2

−bx+25

​

f(x) is continuous at x=5

so there should a factor of (x−5) in x

2

−bx+25

(x

2

−bx+25)=(x−5)(x−5)

f(x)=

(x−2)(x−5)

(x−5)(x−5)

​

=

(x−2)

(x−5)

​

⇒f(5)=0.

Answer 2

Answer:

Step-by-step explanation:

(x2-7x+10)-(x-2)

= x2-7x+10-x+2

=x2-7x-x+10+2

=x2-8x+12

I hope this helps !!
