(x^(2)+8x+15)" by "(x+5)

(a) Find the quare root of (x^(2) - 8x +15) (2x^(2) -11x + 5) (2x^(2) - 7x + 3)

Divide 2x^(3) - 5x^(2) - 8x + 15 by x - 3.

Divide 2x^(3)-5x^(2)-8x+15 by x-3.

Check whether the value of x given against each polynomial is a zero of that polynomial or not : p(x) = x^(2)- 8x + 15, x = 3, 5

Simplify : 1/(x^2 - 8x + 15) - 1/(x^2 - 25)

The solution set of x^(2) - 8x +15 gt 0 is

Value of x for x^(2)-8x +15 = 0 is
