## Answers ( )

Step-by-step explanation:the 9x from the equation can be shifted into the equation and therefore x² + 3 = 9x can be also written as

x² – 9x + 3 = 0

then using the quadratic formula

a = 1

b = -9

c = 3

substitute the values into the equation ,

insert it in your scientific calculator and you will have the answer of

x = 8.65 or x = 0.35

Answer:Step-by-step explanation:Rearrange the given x^2+3=9x in standard quadratic form:

1x^2 – 9x +3 = 0

Then the three coefficients are a = 1, b = -9 and c = 3.

The discriminant is √(b^2 – 4ac), or √(81 – [1][3]), or √78.

± √78Thus, the roots are x = —————-2
