Which equation is quadratic in form? 2(x 5)2 8x 5 6 = 0 x6 6x4 8 = 0 7x6 36x3 5 = 0 4x9 20x3 25 = 0
Amiraneli [1.4K]

The equation that fits the standard form of a Quadratic equation is 2(x + 5)² + 8x + 5 +  6 = 0 which can be re-written as 2x² + 28x + 61 = 0.

<h3>What is a Quadratic Equation?</h3>

Quadratic equation is simply an algebraic expression of the second degree in x. Quadratic equation in its standard form is;

ax² + bx + c = 0

Where x is the unknown

From the given data, we check which of them fits the standard form of a quadratic equation.

  • 2(x + 5)² + 8x + 5+  6 = 0
  • x⁶ + 6x + 4  + 8 = 0
  • 7x⁶ + 36x³ + 5 = 0
  • 4x⁹ + 20x³ + 25 = 0

2(x + 5)² + 8x + 5 +  6 = 0

2( (x(x+5) + 5(x+5) ) + 8x + 5 +  6 = 0

2( x² + 5x + 5x + 25 ) + 8x + 5 +  6 = 0

2( x² + 10x + 25 ) + 8x + 5 +  6 = 0

2x² + 20x + 50 + 8x + 5 +  6 = 0

2x² + 20x + 8x + 50 + 5 +  6 = 0

2x² + 28x + 61 = 0

Therefore, the equation that fits the standard form of a Quadratic equation is 2(x + 5)² + 8x + 5 +  6 = 0 which can be re-written as 2x² + 28x + 61 = 0.

A is (-2,-5) A’is a glide relection where the translation is (x,y) Is(x+7,y) the line of reflection is y=2 What are the coordina
erma4kov [3.2K]

Answer: A' (5,9)


Step-by-step explanation:

1. You have that the translation is (x,y)⇒(x+7,y) and the coordinates of A is (-2,5). Then:

A(-2+7,-5)⇒A(5,-5)

2. As you can see, -5 is 7 units below of the line of reflection y=2, therefore, you can know the coordinates of A' as following:

A'(5,7+2)\\A'(5,9)

3. Then, the coordinates of A' is (5,9)
