Use the distributive property to remove the parentheses.
5b^3(6b^2-4)

Step-by-step explanation:

The distributive property says:

for every a, b, c, (the distributive property over addition)

or (the distributive property over subtraction).

In your case, applying distributive property over subtraction to the expression , you get

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
