Questions How do you expand \( (x+3)^2 \)? More Videos How do you expand \( (x+3)^2 \)? => \( (x+3)^2 \) There are two way to expand \( (x+3)^2 \) First, => \( (x+3)^2 = (x+3) (x+3) \) => \( (x+3)^2 = x (x+3) + 3(x+3) \) => \( (x+3)^2 = x^2 +3x + 3x + 3^2 \) => \( (x+3)^2 = x^2 +6x + 9 \) Second, \( (x+3)^2 \) [use \( (a+b)^2 = a^2 + 2ab +b^2 \)] => \( x^2+2 \times x \times 3 + 3^2 \) => \( x^2+6x + 9 \) Expand Form of \( (x+3)^2 =x^2+6x + 9 \) Related posts: What is The Formula of a plus b plus c Whole Cube?
