Answer:

$\blue{ANSWER}$

(2x+3y+5) (2x+3y-5)

= 2x (2x+3y-5) +3y(2x+3y-5) +5(2x+3y-5)

= 4x²+6xy-10x+6xy+9y²-15y+10x+15y-25

= 4x²+6xy+6xy-10x+10x+9y²-15y+15y-25

= 4x²+12xy+0x+9y²+0y-25

= 4x²+12xy+9y²-25

HOPE IT HELPS UH...!!

A system consists of three masses m₁, m₂ and m₃ connected by a string passing over a pulley P. The mass m₁ hangs freely and m₂ and m₃ are on a rough horizontal table (the coefficient of friction = μ). The pulley is frictionless and of negligible mass. The downward acceleration of mass m1 is : (Assume m₁ = m₂ = m₃ = m) [2014] (a)g(1–gμ )/g (b)2gμ/3 (c)g(1– 2μ )/3 (d)g(1 – 2μ )/2...
