`[{x+2.5}]=`

(2x + 5)(2x - 5) = ?

((5x+2)^(2)+(5x-2)^(2))/((5x+2)^(2)-(5x-2)^(2))=(13)/(12) then find x

The factors of x^4-x^2-10x-25 are (a) (x^2+3x+5)(x^2-3x+5) (b) (x^2+3x+5)(x^2+3x-5) (c) (x^2+x+5)(x^2-x+5) (d) none of these

125^(^^)x=25/(5^(^^)x)

Find lim_(x to 0) ((2+x)^5-2^5)/x

int(x sqrt(x))/(2x^(5/2)+5)dx

The factors of x^(4)+x^(2)+25 are (a)(x^(2)+3x+5)(x^(2)-3x+5)(b)(x^(2)+3x+5)(x^(2)+3x-5)(c)(x^(2)+x+5)(x^(2)-x+5) (d) none of these

(x-2)/(x+5)>2

Simplify (2x+5)^2-(2x-5)^2
