Simplifying
(7w + -9x)(7w + 9x) = 0
Multiply (7w + -9x) * (7w + 9x)
(7w * (7w + 9x) + -9x * (7w + 9x)) = 0
((7w * 7w + 9x * 7w) + -9x * (7w + 9x)) = 0
Reorder the terms:
((63wx + 49w2) + -9x * (7w + 9x)) = 0
((63wx + 49w2) + -9x * (7w + 9x)) = 0
(63wx + 49w2 + (7w * -9x + 9x * -9x)) = 0
(63wx + 49w2 + (-63wx + -81x2)) = 0
Reorder the terms:
(63wx + -63wx + 49w2 + -81x2) = 0
Combine like terms: 63wx + -63wx = 0
(0 + 49w2 + -81x2) = 0
(49w2 + -81x2) = 0
Solving
49w2 + -81x2 = 0
Solving for variable 'w'.
Move all terms containing w to the left, all other terms to the right.
Add '81x2' to each side of the equation.
49w2 + -81x2 + 81x2 = 0 + 81x2
Combine like terms: -81x2 + 81x2 = 0
49w2 + 0 = 0 + 81x2
49w2 = 0 + 81x2
Remove the zero:
49w2 = 81x2
Divide each side by '49'.
w2 = 1.653061224x2
Simplifying
w2 = 1.653061224x2
Take the square root of each side:
w = {-1.285714286x, 1.285714286x}
