(x + 2)(x - 4)

= x^2 - 4x + 2x - 8

= x^2 - 2x - 8

= x^2 - 4x + 2x - 8

= x^2 - 2x - 8

(3x^3 + 2x^5 - 1 + 7x^4) - (5 + 9x^4 + 9x^5 - 5x^3)

= 3x^3 + 2x^5 - 1 + 7x^4 - 5 - 9x^4 - 9x^5 + 5x^3

= 8x^3 - 2x^4 - 7x^5 - 6

= 3x^3 + 2x^5 - 1 + 7x^4 - 5 - 9x^4 - 9x^5 + 5x^3

= 8x^3 - 2x^4 - 7x^5 - 6

(-5 + 6x^7 + 2x^5) + (9x^7 + 5x^5 + 9)

= -5 + 6x^7 + 2x^5 + 9x^7 + 5x^5 + 9

= 4 + 15x^7 + 7x^5

= -5 + 6x^7 + 2x^5 + 9x^7 + 5x^5 + 9

= 4 + 15x^7 + 7x^5

when x = 4 and y = 2,

x^2 + 3y^2 + 2xy

= 4^2 + 3(2^2) + 2(4)(2)

= 16 + 12 + 16

= 28 + 16

= 44

x^2 + 3y^2 + 2xy

= 4^2 + 3(2^2) + 2(4)(2)

= 16 + 12 + 16

= 28 + 16

= 44

(9m + 10)^2

= (9m + 10)(9m + 10)

= 81m^2 + 90m + 90m + 100

= 81m^2 + 180m + 100

= (9m + 10)(9m + 10)

= 81m^2 + 90m + 90m + 100

= 81m^2 + 180m + 100
