Please I need this Answer as soon as possible

Answer 1

`64 - (a + b)^2`

Explanation:

`64 - a^2 - 2ab - b^2\\64 - (a^2 + 2ab + b^2)\\64 - (a + b)^2`

Answer 2

Explanation:

64 - a² - 2ab - b² = 64 -(a² + 2ab + b²)

= 8² - (a +b)² {x² - y² = (x + y)(x -y)

= (8 + a +b) (8 - (a +b))

=(8 +a + b)(8 - a - b)
