Answer 2

Answer 1:- 53*53

(50+3)(50+3)

(50+3)2=a2+b2+2ab

(50)2+(3)2+2*50*3

2500+9+300

Answer 2:-103*96

(100+3)(90+6)

100*90+100*6+3*90+3*6

9000+600+270+18

9888

Answer 3:-(10.2)2

(5.1+5.1)2=a2+b2+2ab

(5.1)2+(5.1)2+2*5.1*5.1

26.01+26.01+52.02

104.04

Answer 4:-(34)2

(30+4)2=a2+b2+2ab

(30)2+(4)2+2*30*4

900+16+240

1156

Answer 5:-(x-6)2

a2+b2-2ab

(x)2+(6)2-2*6*x

x2+36-12x

Answer 6:-(5a-4b)2

a2+b2-2ab

(5a)2+(4b)2-2*5a*4b

25a2+16b2-40ab

Answer7:-(198)2

(100-2)2=a2+b2-2ab

(100)2+(2)2-2*100*2

10000+4-400

9604

Answer8:-(4a)2

(2a+2a)2=a2+b2+2ab

(2a)2+(2a)2+2*2a*2a

4a+4a+8a2

8a2+8a2

16a2

Answer9:-(3x+5)(3x-5)

(3x)2-3x*5+5*3x-5*5

9x-15x+15x-25

9x-25

Answer10:-(33*27)

(30+3)(30-3)

(30)2-30*3+30*3-3*3

900-90+90-9
