Question

100x² + 180x + 81
Solve this PLZ

Answer 1

`(10x + 9 {)}^(2)`

Explanation:

1) Rewrite it in the form a² + 2ab + b², where a = 10x and b = 9.

`(10x) ^(2) + 2(10x)(9) + {9}^(2)`

2) Use square sum: ( a + b )² = a² + 2ab + b².

`(10x + 9 {)}^(2)`

Hence, the answer is (10x + 9)².

Answer 2

`\huge\boxed{\sf (10x+9)^2}`

Explanation:

`\sf 100x^2 + 180x+81\\\\= (10x)^2 + 2(10x)(9)+ (9)^2\\\\Using \ Formula \ a^2 +2ab+b^2 = (a+b)^2\\\\= (10x+9)^2\\\\\rule[225]{225}{2}`

Hope this helped!
