Multiply qrst * i
y = [-1 + 7iqrst + x][x + -1(1 + 7iqrst)]
y = [-1 + 7iqrst + x][x + (1 * -1 + 7iqrst * -1)]
y = [-1 + 7iqrst + x][x + (-1 + -7iqrst)]

Reorder the terms:
y = [-1 + 7iqrst + x][-1 + -7iqrst + x]

Multiply [-1 + 7iqrst + x] * [-1 + -7iqrst + x]
y = [-1[-1 + -7iqrst + x] + 7iqrst * [-1 + -7iqrst + x] + x[-1 + -7iqrst + x]]
y = [[-1 * -1 + -7iqrst * -1 + x * -1] + 7iqrst * [-1 + -7iqrst + x] + x[-1 + -7iqrst + x]]
y = [[1 + 7iqrst + -1x] + 7iqrst * [-1 + -7iqrst + x] + x[-1 + -7iqrst + x]]
y = [1 + 7iqrst + -1x + [-1 * 7iqrst + -7iqrst * 7iqrst + x * 7iqrst] + x[-1 + -7iqrst + x]]

Reorder the terms:
y = [1 + 7iqrst + -1x + [-7iqrst + 7iqrstx + -49i2q2r2s2t2] + x[-1 + -7iqrst + x]]
y = [1 + 7iqrst + -1x + [-7iqrst + 7iqrstx + -49i2q2r2s2t2] + x[-1 + -7iqrst + x]]
y = [1 + 7iqrst + -1x + -7iqrst + 7iqrstx + -49i2q2r2s2t2 + [-1 * x + -7iqrst * x + x * x]]

Reorder the terms:
y = [1 + 7iqrst + -1x + -7iqrst + 7iqrstx + -49i2q2r2s2t2 + [-7iqrstx + -1x + x2]]
y = [1 + 7iqrst + -1x + -7iqrst + 7iqrstx + -49i2q2r2s2t2 + [-7iqrstx + -1x + x2]]
