For this case we have the following expression:
 5x3 + 40y6
 Common factor 5:
 5 (x3 + 8y6)
 Factoring the expression within the parenthesis we have:
 5 ((x + 2y2) (x2 - 2xy2 + 4y4))
 Answer:
 
The factored expression is given by:
 
5 ((x + 2y2) (x2 - 2xy2 + 4y4))

Answer: The expression after completely factorised form is

5[(x+2y^2)(x^2+4y^4-2xy^2)]

Step-by-step explanation:

Since we have given that

5x^3 + 40y^6

We need to factorise it completely:

5x^3 + 40y^6\\\\=5(x^3+8y^6)\\\\=5((x)^3+(2y^2)^3)\\\\=5[(x+2y^2)(x^2+4y^4-2xy^2)]\ (\because\ a^3+b^3=(a+b)(a^2+b^2-ab))

Hence, the expression after completely factorised form is

5[(x+2y^2)(x^2+4y^4-2xy^2)]

Is a triangle with the angles 60 degrees, 40 degrees, and 80 degrees unique?
oksano4ka [1.4K]

Hello,

No a triangle with these angles are not unique. This is because every triangle is supposed to have 180 degrees, just like this one.

Have a great day!
