Answer:

x^{2} + ( 4x) + (147)

Step-by-step explanation:

Here, the given expression is

x^{2} +3x +3 + (2x+134+15) - (x+5)

Now, simplifying the brackets, we get

x^{2} +3x +3 + (2x+134+15) - (x+5) = x^{2} +3x +3 + 2x+134+15 - x -5

Now, operate on the like terms.

= x^{2} + ( 3x + 2x -x) + (134 + 15 + 3 -5)

=x^{2} + ( 4x) + (147)

Hence, the given expression is simplified to the quadratic equation x^{2} + ( 4x) + (147)

For the function
jeka57 [31]

Answer:

x = 1

Step-by-step explanation:

For a quadratic function f(x)=ax^2+bx+c, the axis of symmetry is

x=-\frac{b}{2a}.

This comes from using part of the Quadratic Formula for finding zeros of the function:

x=\frac{-b \pm \sqrt{b^2-4ac}}{2a} = \frac{-b}{2a} \pm \frac{\sqrt{b^2-4ac}}{2a}

See the -b/(2a) in the first term?  That's the x-coordinate of the vertex (turning point) of the parabolic graph of the function.  The axis of symmetry goes through the vertex.
