User: Perform the indicated operation. (2x - 4y)(2x + 4y)

Weegy: 2x - 4y for x = 2 and y = 4;
2(2) - 4(4)
= 4 - 16
= -12



User: Simplify. x2(2x3 - 3) - 3x(x + 4)

User: Write the nth term of the following sequence in terms of the first term of the sequence. 1, 8, 15, 22, . . .

(2x - 4y)(2x + 4y)
= 2x*2x - 4y*2x + 2x*4y - 4y*4y
= 4x^2 - 8xy + 8xy - 16y^2
= 4x^2 - 16y^2

Write the nth term of the following sequence in terms of the first term of the sequence 1, 8, 15, 22, . . . is 7n - 6.
The common difference = 22 - 15 = 7;
nth term = 1 + (n - 1)*7 = 7n - 7 + 1 = 7n - 6

x^2(2x^3 - 3) - 3x(x + 4)
= 2x^5 - 3x^2 - 3x^2 - 12x
= 2x^5 - 6x^2 - 12x

x^2(2x^3 - 3) - 3x(x + 4)
= x^2*2x^3 - x^2*3 - 3x*x - 3x*4
= 2x^5 - 3x^2 - 3x^2 - 12x
= 2x^5 - 12x
