Question

Solve the equation using the quadratic formula. X^2-9x+3=0

Answer 1

Answer:

The answer is x= $\frac{9+\sqrt{69}}{2}$, x= $\frac{9-\sqrt{69}}{2}$

Step-by-step explanation:

x^2=a

-9x=b

3=c

Plug into formula.

Equation: $\frac{9+-\sqrt{(-9)^2-4(1)(3)}}{2}$

Simplify the equation.

Equation: $\frac{9+-\sqrt{81-12}}{2}$

Subtract 81 and 12.

Equation: $\frac{9+-\sqrt{69}}{2}$

Spit into two equations

Equation 1: $\frac{9+\sqrt{69}}{2}$

Equation 2: $\frac{9-\sqrt{69}}{2}$

Hope this helps!
