Find the product of 2y^2 - 3 and y^2 + 3

6y^4 + 3

Step-by-step explanation:

Multiply y^2 by y^2 by adding the exponents.

Move y^2.  

2(y^2 y^2) ⋅ 3+3  

Use the power rule a^m a^n = a^m+n to combine exponents.  

2y^2+2 ⋅ 3+3  

Add 2 and 2.  

2y^4 ⋅ 3+3

Multiply 3 by 2.  

6y^4 + 3

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

thats not a system of equations, that is a solution
