(7m+y)(7m-y)=

Solution for (7m+y)(7m-y)= equation:

Simplifying
(7m + y)(7m + -1y) = 0

Multiply (7m + y) * (7m + -1y)
(7m * (7m + -1y) + y(7m + -1y)) = 0
((7m * 7m + -1y * 7m) + y(7m + -1y)) = 0

Reorder the terms:
((-7my + 49m2) + y(7m + -1y)) = 0
((-7my + 49m2) + y(7m + -1y)) = 0
(-7my + 49m2 + (7m * y + -1y * y)) = 0
(-7my + 49m2 + (7my + -1y2)) = 0

Reorder the terms:
(-7my + 7my + 49m2 + -1y2) = 0

Combine like terms: -7my + 7my = 0
(0 + 49m2 + -1y2) = 0
(49m2 + -1y2) = 0

Solving
49m2 + -1y2 = 0

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add 'y2' to each side of the equation.
49m2 + -1y2 + y2 = 0 + y2

Combine like terms: -1y2 + y2 = 0
49m2 + 0 = 0 + y2
49m2 = 0 + y2
Remove the zero:
49m2 = y2

Divide each side by '49'.
m2 = 0.02040816327y2

Simplifying
m2 = 0.02040816327y2

Take the square root of each side:
m = {-0.142857143y, 0.142857143y}
