Answer:
6x^2+2x-6
Step-by-step explanation:
In the expression (2x)(x2)+(2x)(x)+(2x)(-2)+(3)(x2)+(3)(-2) take each set of two and solve those individually. The expression then becomes 4x^2+2x^2-4x+6x-6 the combining like terms you get 6x^2+2x-6.
Answer:
(-6, -2)
Step-by-step explanation:
When trying to find the solution to a system of equations on a graph, the solution is where the lines intersect.
The lines intersect at (-6, -2). This is the solution.

ANSWER
D) 10
EXPLANATION
We want to solve the radical equation,

Square both sides,

Expand brackets on right hand side,

Rewrite in general quadratic equation form,

Factor to obtain,

Apply the zero product principle to get,

We put n=2 into the equation to get,


This statement is false, hence 2 is an extraneous solution
We put n=10, to get



This is true, hence the only solution is
