Answer to Problem 3AR

The solution of equation is either y=9 or y=2

Explanation of Solution

Given information:

The quadratic equation y27y18=0

Concept and Formula Used:

Quadratic formula x=b±b24ac2a where quadratic equation is ax2+bx+c=0

Solving using factoring can be done by splitting the middle term of equation and then making groups and equating them to zero.

Calculation:

It is given that

  y27y18=0

Solving equation using quadratic formula x=b±b24ac2a

Where a=1,b=7&c=18

Putting the values in the formula

  y=(7)±(7)24×(1)×(18)2(1)y=7±49(72)2y=7±1212y=7±112

Therefore either y=7+112=182 or y=7112=42

Either y=9 or y=2

Conclusion:

The solution of equation is either y=9 or y=2
