Question

send me the correct and quick answer ​ ​

Answer 1

Answer:

5)we have to prove the value of P0), P(3)

then

given that P(y) =y^2-9

P(0) =(0)^2-9=0-9= -9

P(3) =3^2-9=9-9=0

6) (x+3)(x+8)

x^2+8x+3x+24

x^2+11x+24

7)(3x-2)(3x-6)

(3x)^2-18x-6x+12

9x^2-24x+12

8)49x^2-42x+9

49x^2-21x-21x+9

7x(7x-3)-3(7x-3)

(7x-3)(7x-3)

9)169x62-625

(a+b)(a-b)=a^2-B^2

then the given form can be writen as

(13X)^2-625

(13x)^2-(25)^2

(13x+25)(13x-25)

10)
