If `=|-x a bb-x a a b-x|` , then a factor `` is `a+b+x` `x^2-(a-b)+x+a^2+b^2+a b` `x^2-(a+b)+x+a^2+b^2-a b` `a+b-x`

x^2-a x-b x+a b

Solve for 'x' and 'y': (a -b) x + (a + b) y =a^2 - b^2 - 2ab (a + b) (x + y) = a ^2+ b^2

Let a,b>0 and Delta=|(-x,a,b),(b,-x,a),(a,b,-x)| then (1) a+b-x is a factor of Delta 2) x^2+(a+b)x+a^2+b^2-ab is a factor of Delta (3) Delta=0 has three real roots if a=b 4) all of these

(x + a) (x + b) = x^(2) + (a + b)x + ________.

The factors of |(x,a,b),(a,x,b),(a,b,x)| , are

Find a and b, if x+1 and x+2 are the factors of x^(3)+3x^(2)-2ax+b.

(a-b)x+(a+b)y=a^(2)-2ab-b^(2)(a+b)(x+y)=a^(2)+b^(2) find x and y

If x+2 is a factor of both x^2+ax+b and x^2+bx+a then a/b=
