1 answer:

8 0

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.
