Question

(4y+8)(5y−9)

Answer 1

[AI-generated answer — Bot GPT 3.5]

= 4y(5y) + 4y(-9) + 8(5y) + 8(-9)

= 20y^2 - 36y + 40y - 72
= 20y^2 + 4y - 72

Answer 2

(−2y+5)(2y^6+4y+2)

Answer 3

[AI-generated answer — Bot GPT 3.5]

= -2y(2y^6) - 2y(4y) - 2y(2) + 5(2y^6) + 5(4y) + 5(2)

= -4y^7 - 8y^2 - 10y + 10y^6 + 20y + 10
= -4y^7 + 10y^6 - 8y^2 + 10y + 20

Answer 4

(3y+3)(4y^4+3y+4)

Answer 5

[AI-generated answer — Bot GPT 3.5]

= 3y(4y^4) + 3y(3y) + 3y(4) + 3(4y^4) + 3(3y) + 3(4)

= 12y^5 + 9y^2 + 12y + 12y^4 + 9y + 12
= 12y^5 + 12y^4 + 9y^2 + 21y + 12

Answer 6

(3y+10)(2y^4+3y−7)

Answer 7

[AI-generated answer — Bot GPT 3.5]

= 3y(2y^4) + 3y(3y) + 3y(-7) + 10(2y^4) + 10(3y) + 10(-7)

= 6y^5 + 9y^2 - 21y + 20y^4 + 30y - 70
= 6y^5 + 20y^4 + 9y^2 + 9y - 70

Answer 8

(−3y^3+8)(4y^8+7y+2)

Answer 9

[AI-generated answer — Bot GPT 3.5]

= -3y^3(4y^8) -3y^3(7y) -3y^3(2) + 8(4y^8) + 8(7y) + 8(2)

= -12y^11 - 21y^4 - 6y^3 + 32y^8 + 56y + 16
= -12y^11 + 32y^8 - 21y^4 - 6y^3 + 56y + 16
