Answer:

4x^2 + 12x + 9

Step-by-step explanation:

Actually, you are to find (2x + 3)^2, which is "the square of 2x + 3."

2x + 3 is a binomial.  There is a formula for the square of a binomial:

(a + b)^2 = a^2 + 2ab + b^2

Following this pattern,

(2x + 3)^2 becomes:

[2x]^2 + 2[2x][3] + [3^2], or

4x^2 + 12x + 9

You solved a linear system with two equations and two variables and got the equation o=-8. how many solutions does the system of
Luda [366]
If you simplified a two-equation system and all variables were eliminated, two outcomes are possible.

If the final equation is a true equation, like 3=3, then the system has an <em>infinite number of solutions </em> (the equations graph the same line, and all points appear on both graphs)

If the final solution is a mathematically false equation, like 0=-8, the system has no solution. The lines are parallel and never intersect (have a solution)
