What is 105^2 using the polynomial identity (a+b)^2=a^2+2ab+b^2 ? Drag and drop the correct responses into the boxes.
105^2 11025 21 5+100 5^2 x 5 x 100+100^2 5^2 x 5 x 21+21^2 1105 100 5

Let the smaller value a = and the larger value b = ___ . Then a^2+2ab+b^2 is . This can be simplified to . So, 105^2 is equal to .
