Solve for [tex]$x$[/tex]

[tex]\[ x^2 - 2x + 30 = 0 \][/tex]


Sagot :

Certainly! Let's solve the quadratic equation [tex]\( x^2 - 2x + 30 = 0 \)[/tex] step by step.

The general form of a quadratic equation is [tex]\( ax^2 + bx + c = 0 \)[/tex]. Here, [tex]\( a = 1 \)[/tex], [tex]\( b = -2 \)[/tex], and [tex]\( c = 30 \)[/tex].

To find the roots of the quadratic equation, we use the quadratic formula:

[tex]\[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \][/tex]

First, let's calculate the discriminant, which is the expression under the square root in the quadratic formula:

[tex]\[ \Delta = b^2 - 4ac \][/tex]

Substitute [tex]\( a = 1 \)[/tex], [tex]\( b = -2 \)[/tex], and [tex]\( c = 30 \)[/tex] into the discriminant formula:

[tex]\[ \Delta = (-2)^2 - 4 \cdot 1 \cdot 30 \][/tex]
[tex]\[ \Delta = 4 - 120 \][/tex]
[tex]\[ \Delta = -116 \][/tex]

The discriminant, [tex]\(\Delta\)[/tex], is [tex]\(-116\)[/tex]. Since the discriminant is less than zero, we conclude that:

1. The discriminant is negative, which means the equation has no real roots.

Thus, the solution to the quadratic equation [tex]\( x^2 - 2x + 30 = 0 \)[/tex] is that it has no real roots.
