Question

x^7y-2xy+4x^3-4

Answer 1

=8x+14-6x+12
=2x+26

Simplifying it is the only option to solve it ,as you haven't given a y value or x value.

Answer 2

Simplifying
2(4x + 7) + -3(2x + -4)

Reorder the terms:
2(7 + 4x) + -3(2x + -4)
(7 * 2 + 4x * 2) + -3(2x + -4)
(14 + 8x) + -3(2x + -4)

Reorder the terms:
14 + 8x + -3(-4 + 2x)
14 + 8x + (-4 * -3 + 2x * -3)
14 + 8x + (12 + -6x)

Reorder the terms:
14 + 12 + 8x + -6x

Combine like terms: 14 + 12 = 26
26 + 8x + -6x

Combine like terms: 8x + -6x = 2x
26 + 2x
