Question

plz help me to solve the question... class 7 .....math...​

Answer 1

Step-by-step explanation:

(1+m)²=(1-m)²+41m

1²+2×1×m+m² = 1²-2×1×m+m² +41m

1+2m+m² =1-2m+m²+41m

cancel 1&m²

then u will get , 2m = -2m + 41m

2m = 39m

39m - 2m = 1

37m = 1

value of m = 1/37

I think it's the right answer .

Answer 2

(1+m)²=(1-m)²+41

1+m²+2m=1+m²-2m+41

m²-m²+2m+2m=41-1+1

4m=41

m=41/4

m=10.24
