Factorise: x^(2) + 8x +15

Solve the following quadratic equation x^(2) + 8x +15 =0

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

In how many points will the graph of x^(2) +8x + 15 intersect X - axis? Why?

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

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

B= [x//x^(2)-x-12=0} C={x//x^(2) -8x + 15 =0, then B uuC=

B= [x//x^(2)-x-12=0} C={x//x^(2) -8x + 15 =0, then B uuC=

x^(2) -8x + 15=0, y^(2)-3y +2=0

Check whether '6' becomes a zero of x^(2) +8x +15 or not? Give reasons.
