Use the zero product property
x - 3 = 0, and x - 2 = 0
x = 3, and x = 2

The roots of a quadratic equation ax2+bx+c=0 are 1+i 5 and 1−i 5 . Find possible values of a, b and c.
Anarel [89]

Answer:

Step-by-step explanation:

If the roots are 1 + 5i and 1 - 5i, then you need the factors that result from those roots.  They are (x - 1 + 5i) and (x - 1 - 5i).  Now what you do with those is FOIL them out.  Doing that gives you the following:

x^2-x+5ix-x+1-5i-5ix+5i-25i^2 (what a mess, huh?)

The good thing is that several of those terms cancel each other out.  +5ix cancels out the -5ix; -5i cancels out the 5i; and the 2 -x terms combine to -2x.  That leaves you with:

x^2-2x-25i^2

Obviously you're in the section in math that deals with complex (imaginary) numbers so you should know that i-squared is equal to -1.  Making that replacement:

x^2-2x+25

a = 1, b = -2, c = 25

Hi there!

\large\boxed{b = \frac{a}{ac - 1}}

We can begin by making each fraction have a common denominator:

If we make each have a common denominator of ab, we get:

\frac{b}{ab} + \frac{a}{ab} = c

Simplify:

\frac{a + b}{ab}  = c

Multiply both sides by ab:

a + b = cab

Move b to the opposite side:

a = cab - b

Factor out b:

a = b(ac - 1)

Divide by (ac - 1):

\frac{a}{ac - 1} = b
