Expand the polynomial and simplify: (4xy− 1 8 y^2)^2

Vinvika [58]

Answer: $4y^{2}(2x-9y)^{2}$

Step-by-step explanation:

We have the following polynomial:

$(4xy-18y^{2})^{2}$

This is a polynomial of the form $(a-b)^{2}=a^{2}-2ab+b^{2}$ . Following this rule to expand it, we have:

$(4xy)^{2}-2(4xy)(18y^{2})+(18y^{2})^{2}$

$16x^{2}y^{2}-144xy^{3}+324y^{4}$

Applying common factor $4y^{2}$ :

$4y^{2}(4x^{2}-36xy+81y^{2})$

Note the polynomial inside the parenthesis is a perfect square trinomial, which can be factored to $(2x-9y)^{2}$ . Hence, the final simplification is:

$4y^{2}(2x-9y)^{2}$

Find the value of x and then the measure of each angle. You should have 3 answers.

Softa [21]

Answer:

x = 7

3x + 11 = 32

8x + 2 = 58

Step-by-step explanation:

3x + 11 + 8x + 2 = 90

11x + 13 = 90

11x = 77

x = 7

3x + 11 = 3(7) + 11 = 32

8x + 2 = 8(7) + 2 = 58
