Expand : ( X - 2y + 2 )2 - Mathematics

Expand : ( x - 2y + 2 )²

Sum

( x - 2y + 2 )²= x² + (2y)² + (2)² - 2(x)(2y) - 2(2y)(2) + 2(2)(x)
= x² + 4y² + 4 - 4xy - 8y + 4x

Expand : ( x - 8 )( x - 10 )

Expand : ( x + y - z )²

In the expansion of (2x² - 8) (x - 4)²; find the value of constant term.

If a² + b² = 34 and ab = 12; find : 3(a + b)² + 5(a - b)²

If a² + b² = 34 and ab = 12; find : 7(a - b)² - 2(a + b)²

If 3x - `4/x` = 4; and x ≠ 0 find : 27x³ - `64/x^3`
