X^2-9x+14=0

X= -(-9)+_square root(-9)^2-4(1)(14)/2

X= 9+_Square Root 25/2

X= 9+_5/2

X= 9+5/2= 7

X= 9-5/2= 2

The Answer is: 7and 2.

x^(2) -9x+14=0\\x= \frac{-b+- \sqrt{b^(2)-4ac}}{2a} \\x=\frac{-(-9)+- \sqrt{(-9)^(2)-4(1)(14)}}{2(1)}\\x=(9+- √(81-56))/(2)\\x=(9+- √(25))/(2)\\x=(9+-5)/(2)\\x=(4, 14)/(2)\\x=2, 7
