Stuck on two math problems, can anyone help me?

Question

Find each of the following squares. (3a - 4b)^2

Find each of the following products. 5w(2w - z)(2w + z)

Answer 1

First question: 9a^2-24ab+16b^2
Second question: 5w(4w^2-z^2)=20w^3-5wz^2

Answer 2

First problem: if the top result's two better than then volume, accurate part should be 2 + z 2(z+3) = 2 + z 2z + 6 = 2 + z 2z - z = 2 - 6 z = -4 (also, effect of your equation might want to were z = -a million a million/3, no longer a million a million/3) ==================== 7 better than the volume is 7+z, so left part should be 3z + (7+z) 3z + 7 + z = -11 - 2z 4z + 2z = -11- 7 6z = -18 z = -3

Answer 3

(3a-4b)^2

(3a-4b)(3a-4b) Foil (first outer inside last)

9a^2-12ab-12ab+16b^2 Then add like terms

9a^2-24ab+16b^2



Second problem:

5w(2w-z)(2w+z) First multiply the (2w-z)(2w+z)

5w(4w^2-2wz+2wz-z^2) Combine like terms

5w(4w^2-z^2) Distribute

20w^3-5wz^2

Answer 4

(3a-4b)(3a-4b) foil
9a^2 - 12ab -12ab + 16b^2 Combine like terms
= 9a^2 - 24ab + 16b^2

5w(2w - z)(2w + z) Foil the second and third factors together
5w(4w^2 -z^2) distribute the 5w
20w^3 - 5wz^2

Answer 5

(3a-4b)(3a-4b) 9a^2 - 12ab -12ab + 16b^2 = 9a^2 - 24ab + 16b^2
i think thats right. Oh well good luck to the person who gets chosen for best

Answer 6

Use the FOIL Method when multiplying binomials. The first answer is 9a(squared)-24ab+16b(squared). The second is 20w(cubed)-5wz(squared).

Answer 7

Question 1
(3a - 4b).(3a - 4b) = 9a² - 24ab + 16b²

Question 2
5w.(4w² - z²) = 20w³ - 5wz²

Answer 8
