(a + x^2)(b + y^2)
a(x + y - z)
xy + ay + ab + bx = y(x + a) + b(a + x) = y(x + a) + b(x + a) = y(x + a) + b(x + a) = (y + b)(x + a) To check, multiply out the two brackets making sure that each pair is evaluated.
Ab + xy ---> ay + xb
A double replacement reaction.
Double Replacement
The problem here is nobody knows if "ay squared" is (ay)2 or ay2 etc. To solve a mathematical problem it must be set out mathematically or nobody knows your intention. Here is a sort of mathematical statement which is unclear, and although it ends in a question mark, nobody knows what the question is, even if you do. Try again and people will do their best to answer it. I read the question as: x2y2 + ay2 + ab + bx2 ? But what is required to be done with it?
a(x + y + z)
Recall distributivity a(b + c) = ab + ac = (b + c)a and associativity (ab)c = a(bc) (a + b) + c = a + (b + c) as well as commutativity ab = ba a + b = b + a we are gonna need those. See for yourself when I applied each to learn the trick: ax - bx - ay + yb = (ax - bx) + (-ay + yb) = x(a - b) + -y(a - b) = (x - y)(a - b)
ax + ay - AZ = a(x + y - z)
a(x + y - z)
xy + ay + ab + bx = y(x + a) + b(a + x) = y(x + a) + b(x + a) = y(x + a) + b(x + a) = (y + b)(x + a) To check, multiply out the two brackets making sure that each pair is evaluated.
Ab + xy ---> ay + xb
Ab, Ad, Ah, AI (Abbr.), Al (Name), An, As, At, Ay (Shakespearean).
(a - b)(x + y)
PUSH ay tulak, yung PULL ay pahatak.
(G+g)ay
ang binary ay o mas tawag sa (AB) ang unang tono ay iba sa pagalawang tono
