Explanation:
The two brackets are multiplied by each other.
- To start, multiply the first term in the first bracket by the first term in the second bracket.
#=(x)(x) = x^2#
In other words, x squared or x to the power of two.
For right now, your equation is:
#x^2# -
Multiplying the first term in the first bracket (
# x# ) by the second term in the second bracket =#(-2)#
Your equation will now become:
#x^2-2x# -
multiplying the second variable in the first bracket by the first variable in the second bracket.
This is going to be#(3)(x)#
Your equation will now become:
#x^2-2x+3x# -
You now have to multiply the second term in the first bracket by the second term in the second bracket.
This is going to be#(3).(-2)#
Your equation will now look like
- Next step
You need to combine like variables.
You now have your simplified answer
