Question

what is (x+a)×(y+a) ​

Answer 1

Answer:

Powers

x a x b = x (a + b)

x a y a = (xy) a

(x a) b = x (ab)

x (a/b) = bth root of (x a) = ( bth (root)(x) ) a

x (-a) = 1 / x a

x (a - b) = x a / x b

 

Logarithms

y = logb(x) if and only if x=b y

logb(1) = 0

logb(b) = 1

logb(x*y) = logb(x) + logb(y)

logb(x/y) = logb(x) - logb(y)

logb(x n) = n logb(x)

logb(x) = logb(c) * logc(x) = logc(x) / logc(b)

Answer 2

• (x-a)(x-b) is equal to x^2-xb-ax-ab= x^2 -x(b+a) –ab or = x^2 -b(x+a) –ax. The x minus a and b takes the quadratic formula and includes steps that should govern with above formula by operating and come across in an identify of same sort
