(4u+5v)(4u-5v)(u) = (16u^2 -25v^2) u = 16u^3 -25v^2 u
you just have to multiply out the 3 terms. ..

When you have
(a+b)(a-b)
The answer is
a^2 - b^2
In your case a=4u, so a^2=16u^2,
while b = 5v, so b^2=25v^2
16 u^2 - 25 v^2
Then you just multiply u into both terms
16 u^3 - 25 u v^2

word the definition of artwork , that's the dot manufactured from tension and displacement of the factor OF utility OF tension. So , F.s = W, now each so often artwork would nicely be equivalent to means, evaluate a physique located at frictionless floor and we push it such that physique starts to go, right here if no loss of means(as we've seen frictionless floor), total artwork that we did is converted to means,right here one million/2*m*v*v = F.s, (as one million/2*m*v*v is kinetic technique of physique), in any different case it is not constantly actual. For greater clearance i propose you to envision suggestions of Physics by making use of sir H.C. Verma financial disaster call artwork & means.

What question? If you want to expand the product, multiply the first term by the second term and then multiply the resulting product by the third term.

(4u*4u + 5v*4u - 4u*5v - 5v*5v)*u=
(16u^2 + 20vu - 20vu - 25v^2)*u=
(16u^2 - 25v^2)*u=
16u^3 - 25v^2u
