Question

solve by using quadratic formula :x²-3x+1=0​

Answer 1

Answer:

How do you solve the quadratic equation x2+3x−1=0 by completing the square? Hint: To solve the quadratic equation by completing the square we have to transform the equation in (x+a)2=b2 . As there is 3 in the coefficient of x we can write 3x as 2⋅32x and we will add 94 both sides of the equation.

Answer 2

Step-by-step explanation:

$x = \frac{ - ( - 3) + \sqrt{ {( - 3)}^{2} - 4 \times 1 \times 1 } }{2 \times 1} \: and \: \frac{ - ( - 3) - \sqrt{ {( - 3)}^{2} - 4 \times 1 \times 1} }{2 \times 1} \\ = \frac{3 + \sqrt{9 - 4} }{2} \: and \: \frac{3 - \sqrt{9 - 4} }{2} \\ = \frac{3 + \sqrt{5} }{2} \: and \: \frac{3 - \sqrt{5} }{2}$
