Simplifying
J = (x + 7)(5x + -1) + -1(x + 7) * x

Reorder the terms:
J = (7 + x)(5x + -1) + -1(x + 7) * x

Reorder the terms:
J = (7 + x)(-1 + 5x) + -1(x + 7) * x

Multiply (7 + x) * (-1 + 5x)
J = (7(-1 + 5x) + x(-1 + 5x)) + -1(x + 7) * x
J = ((-1 * 7 + 5x * 7) + x(-1 + 5x)) + -1(x + 7) * x
J = ((-7 + 35x) + x(-1 + 5x)) + -1(x + 7) * x
J = (-7 + 35x + (-1 * x + 5x * x)) + -1(x + 7) * x
J = (-7 + 35x + (-1x + 5x2)) + -1(x + 7) * x

Combine like terms: 35x + -1x = 34x
J = (-7 + 34x + 5x2) + -1(x + 7) * x
