IS THERE ANYONE WHO IS A GOD AT MATH? AND CAN ANSWER THESE QUESTIONS PLEASE IM HORRIBLE AND NEED HELP?

Question

1.Simplify the expression "(3x + 2)(3x + 2)".

2.How do you determine the degree of a polynomial? If a fourth-degree polynomial is multiplied by a third-degree polynomial, what is the degree of the product? Explain your reasoning and provide examples to support your explanation

Answer 1

1. Well, if by simplify you mean cut it down... I guess (3x+2)^2 is what you want? Or you could mean foiling it, which gives you 9x^2+12x+4.

2. You determine the degree of a polynomial by its largest exponent. For example, "x^5+1" is a degree of 5 regardless of what comes after "x^5". So the only thing you have to worry when finding the degree of multiplied polynomials is the product of the highest exponents. So when a third-degree and a fourth-degree is multiplied, (x^3)*(x^4) results in x^7, so the final degree is 7.

Answer 2

1.i believe that the simplified form for (3x+2)(3x+2) is (9x^2+12x+4)

2.you determine the degree of a polynomial by looking at the highest exponent of the expression..

for example:

a.) 4x^6+5   ->this has a degree of six(6)

b.) x^3+x^9+6+x  ->this has a degree of nine since 9 is the HIGHEST exponent..

if you multiply a third degree w/ a 4th degree you would get a seventh degree polynomial.when multiplying polynomials, you would just add the degree of the terms being multiplied.

example:

a).(3^x4+4x^5)(2x^5)=(6x^9+8x^10)

hope that answers your question...and by the way iam not a math god..lol  

Answer 3

1. (3x+2)(3x+2)

   = 9x²+6x+6x+4

   = 9x²+12x+4

2. ex. x4(degree) multiplied by x³ = x 7th degree

because if a fourth degree multiplied by a third-degree polynomial the product = the fourth degree add by third degree so 4+3 = 7 then the degree is 7 .

i hope it would b help ..

Answer 4

1. this is basically (a+b)^2

   and the answer of this is always  a^2+ 2ab+ c^2

   so the answer is

   9x^2+12x+4

2. whenever you multiply two polynomials u add the powers same in this case. 4+3=7

x^4*x^3= x^7

Answer 5

Sorry, the only math god I know of was this golden calf guy. He was GREAT at math, could do any problem you gave him. But then this other god came and had him melted. That sucked.
