Answer:

A= (3*X - 6\sqrt{x})/(X-4)

A=(3*2 - 6\sqrt{2})/(2-4)= -3+3\sqrt{2}

A=(3*4 - 6\sqrt{4})/(4-4) Unknown

Find the x-intercepts for the parabola defined
Inessa05 [86]

Answer:

<h2>Explanation:</h2>

In this exercise we have the following equation of a parabola:

y=2x^2-12x+10

So our goal is to find the x-intercepts. We can find this setting y=0, so:

2x^2-12x+10=0

Taking 2 as common factor:

2(x^2-6x+5)=0

Hence this is a Non-perfect Square Trinomial. To factor out this, let's choose two numbers such that:

  • The sum is -6
  • The product is 5

Those two numbers are:

  • -1 and -5

Because:

  • Sum: -6
  • Product: 5

So this equation can be written as:

x^2 + (a + b)x + ab=(x + a)(x + b) \\ \\ a=-1 \\ b=-5 \\ \\  x^2-14x+24=(x-(-1))(x-(-5))=0 \\ \\ (x+1)(x+5)=0 \\ \\ So \ the \ solutions \ are: \\ \\ \boxed{x=-1 \ and \ x=-5}

We\ will\ use\ PEMDAS.

Parenthesis

Multiplication
Division
Addition
Subtraction

We\ do\ the\ multiplication\ and\ division\ first\ as\ there\ are\ no\\&#10;parenthesis\ and\ exponents\ in\ the question.
\\3 - 3\times6 + 2 =\\ 3 - 18 + 2 =\\ Now\ we\ just\ add\ and\ subtract\ what\ is\ left.\ :)\\ \fbox{We\ go\ from\ left\ to\ right.}\\ 3 - 18 = -15\\ -15 + 2 = -13\\ \\ The\ answer\ is\ \fbox{-13}.
