answer please

Answer 1

Answer:

(i) (2x)² + (2)(2x)(3y) + (3y)² = (2x+3y)²

(ii) (x)² + (2)(x)(11) + (11)² = (x+11)²

(iii) (3x)² + (2)(3x)(-4y) + (-4y)² = (3x-4y)²

(iv) (6x)² + (2)(6x)(-3) + (-3)² = (6x-3)²

(v) (4x²)² - (2)(4x²)(9y²) + (-9y²) = (4x²-9y²)²

(vi) (m)² + (2)(m)(4) + (4)² = (m+4)²

(vii) (6x)² + (2)(6x)(7y) + (7y)² = (6x+7y)²

(viii) (3a)² + (2)(3a)(7b) + (7b)² = (3a+7b)²
