Question

Solve for


$a + b + x \: is \: not \: equal \: to \: 0 \: \\ a .b.x \: not \: equa \: to \: zero$


$\frac{1}{a + b + c} = \frac{1}{a} + \frac{1}{b} + \frac{1}{c}$
​

Answer 1

Step-by-step explanation:

Subtract 36 from both sides

x

2

−

5

x

−

36

=

0

This is the equation of a quadratic so wee need the x-intercepts.

Two numbers that multiply to 36 are 4 and -9, and they add to -5 so your equation can be

(

x

+

4

)

(

x

−

9

)

=

0

so

x

=

−

4

,

9
