`(2x+6)/(x+2)^2-2/(x+2)`
THe expression above is equivalent to `a/(x+2)^2` where a is a positive constant and `x ne -2`
What is the value of a?

(x^(2)-4x-5)/((x-1)^(2)-4(x-1)) The expression above is equivalent to

(x^(2)+9x-22)/(x^(2)-121) ÷ (2-x) The expression above is equivalent to

The expression x^(2)-7x+12 is equivalent to :

If x is a positive integers and x+12=x^(2) , what is the value of x?

((9)/(4)x^(2)-1)-((3)/(2)x-1)^(2) The expression above is equivalent to

If x-3 is a factor of ax^(2)-a^(2)x+12 , where a is a positive constant, what is the value of a ?

The expression 1/3x^2-2 can be rewritten as 1/3(x-k)(x+k) , where k is a positive constant . What is the value of k ?

The expressions 4x^(2)-12 is equivalent too 4(x+c)(x-c) . If c is a positive constant, what is the value of c?

(-3x^(2) + 5x -2) -2(x^(2)-2x-1) If the expression above is rewritten in the form ax^(2) + bx +c , where a, b, and c are constants, what is the value of b ?
