pls answer this question fast pls ​

Answer 1

Hey buddy, I am just writing the main answers. You insert them in your answer

(I)1) 14n

(I)2) 10x

(I)3) 6b

(I)4) x^2

(I)5) 25q^2

(II)1) d^2 - 6d + 9

=> (a-b)^2 = a^2 - 2ab + b^2

=) a^2 -> d^2

   2ab -> 6d

   b^2 -> 9

=> a = √d^2 = d

    b = √9 = 3

=> (d-3)^2 = d^2 - 6d + 9

(II)2) y^2 - 8y + 16

=> (a-b)^2 = a^2 - 2ab + b^2

=) a^2 -> y^2

   2ab -> 8y

   b^2 -> 16

=> a = √y^2 = y

    b = √9 = 3

=> (y-3)^2 = y^2 - 8y + 16

(III)1) 7ab + 9cd + 7ad + 9bc

=> (7ab+9bc) + (7ad+9cd)

=> b(7a+9c) + d(7a+9c)

=> (b+d)(7a+9c)

(III)2) px + qx + py + qy

=> (px+py) + (qx+qy)

=> p(x+y) + q(x+y)

=> (p+q)(x+y)

Answer 2

Answer:

1. n^2 + 14n+49

2. x^2 - 10x + 25

3 b^2 - 6b + 9

4 x^2 + 16x + 6

5 p^2 -10pq + (5q) ^2

Q2. 1) d^2 - 6d +9

= d^2 -3d - 3d + 9

= d(d - 3) - 3(d-3)

= (d -3)(d -3)

2)
