The Intersecting Secant Theorem says

EC × ED = EB × EA

(x+4)(x+4+1) = (x+1)(x+1+11)

(x+4)(x+5)=(x+1)(x+12)

x^2 + 9x + 20 = x^2 + 13 x + 12

8 = 4x

x = 2

Check:

6(7)=42

3(14)=42, good

Answer: 2

What is the multiple zero and multiplicity of f(x)=x^3-14x^2+49x
Stella [2.4K]
X^3 - 14x^2 + 49x = 0

Factor an x out:

x(x^2 - 14x + 49) = 0

Find two factors of 49 that add to -14 (-7 and -7). Convert the trinomial to two binomials:

x(x - 7)(x - 7) = 0

The zeros are:

x = 0 and x = 7.

7 occurs as a zero twice and therefore has a multiplicity of 2.
