Rearrange this expression into quadratic form, ax2 + bx + c = 0; 0.20 = x2 / (85 - x).
An algebraic expression in the form of ax2 + bx + c = 0 is called a quadratic equation. It has a degree value of 2.
Answer: 0.20 = x2 / (85-x) can be arranged in the quadratic form as 5x2 + x - 85 = 0.
Let us proceed step by step.
Explanation:
Let us simplify the given equation: 0.20 = x2 / (85 - x)
⇒ 0.20 = x2 / (85 - x)
⇒ 20/100 = x2 / (85 - x)
⇒ 1/5 = x2 / (85 - x) [ reducing to lowest form]
⇒ 5x2 = 85 - x [ cross multiplying the terms ]
On rearranging we get 5x2 + x - 85 = 0
Where a = 5, b = 1 and c = -85
Therefore, 0.20 = x2 / (85 - x) can be arranged in the quadratic form as 5x2 + x - 85 = 0.
