Expert Solution & Answer

Chapter 1.5, Problem 3P

Solution

To calculate: The solution of the quadratic equation 9x2−30x+25=0 .

The solution is x=53 .

Given information:

The equation is 9x2−30x+25=0 .

Calculation:

Consider the given equation,

9x2−30x+25=0

Find two real numbers such that product is 9×25=225 and sum is −30 . So, −15 and −15 are two numbers, which product is 225 and sum is −30 . So,

9x2−30x+25=09x2−15x−15x+25=0

Factor the equation by regrouping.

9x2−15x−15x+25=03x3x−5−53x−5=03x−52=0

Take square root on both sides and simplify

3x−5=03x−5=03x=5x=53

Therefore, the solution of the given equation is x=53 .
