We split 135 into 100 + 30 + 5 and expand it using the three-term identity. Summing the separate square values and their paired products provides the final answer.
Select and use the identity that will help you to find the product without multiplying directly: (135) square

We find this large square value by splitting 135 into a three-part addition expression, 100 + 30 + 5. This allows us to apply the three-term identity where a is 100, b is 30 and c is 5. The three individual squares are 10000, 900 and 25. The double cross-products are 6000, 300 and 1000. Summing all these evaluated values together gives 18225.
