Hey there!
Answer = [tex]x^{2}+2x[/tex]
Explanation:
Let's simplify step-by-step.
x(x + 3) -x
Distribute:
= (x)(x) + (x)(3) + -x
= [tex]x^{2}+3x+-x[/tex]
Combine Like Terms:
= [tex]x^{2}+3x+-x[/tex]
= [tex](x^{2})+(3x+-x)[/tex]
= [tex]x^{2}+2x[/tex]
So therefore, that is how you found your answer: [tex]x^{2}+2x[/tex]
