how will answer this question I will mark as Brainly list ok​

Answer 1

Answer:

It easy

Step-by-step explanation:

y2-5 y2-3

=y2+(-5-3)y+-3×-5

y2-8 y+15

ii)(102) (106)

=(100+2)(100+6)

= here, 100 = x, 2= a and 6 = b

so use this formula

(x+a)(x+b)

which I used in I) solution

3 soln) same ....

4 soln) (40+1)2

= (a+b)2 mean a+b whole square

therefore

40^2 + 2×40×1+ 1^2

1600+80+1

1681

5 soln) (50+3)2

same

6soln) here u can use (a+b)2 or ( a-b)2

(60-1)2 or (50+9)2

same

7soln) here (a+b)2

= 3x2+2×3x×5+5^2

= 9x^2+30x+25

8 soln) same as 1,2

Now everything is same u can take idea do it will help u if u can't do just tell I'm here to help u my frnd
