Linear Equation in 2 Variables

Expand : 3x+...

Question

Expand :
$(3 x + 4 y - 5 p)^{2}$

Open in App

Solution

On expansion we get,

$(3 x + 4 y - 5 p)^{2}$

$⟹ (3 x)^{2} + (4 y)^{2} + (- 5 p)^{2} + 2. (3 x) (4 y) + 2. (4 y) (- 5 p) + 2. (3 x) (- 5 p)$

$⟹ 9 x^{2} + 16 y^{2} + 25 p^{2} + 24 x y - 40 p y - 30 p x$
