Hence the solution is a radius of 0.32 cm. We can check this value of 0.32 cm by substitution in the equation 2 = r2 + 6r. Hence 0.10 + 1.92 = 2.02, which is effectively 2 bearing in mind the rounding of the roo
This quadratic equation only has a single solution, at x = -2/3. Notice that this will be the case anytime the value under the square root in the formula is zero. The value under the square root in the quadratic formula, {eq}b^2 - 4ac {/eq}, has a unique name. It is called...
Using this formula, you can find the solutions to any quadratic equation. Note that there are three possible options for obtaining a result: The quadratic equation has two unique roots when Δ > 0. Then, the first solution of the quadratic formula isx₁ = (-B + √Δ)/2A, and the ...
, the calculator would find the roots x = 0.5 and x = -3. If given the quadratic equation , the calculator would find the roots in complex form as x = -1 + 2i and x = -1 - 2i, whereirepresents the imaginary unit. Quadratic Equation Solution A quadratic equation is a second-ord...
500 BC represent solutions of the equation, but even should this be the case, there is no record of the method of solution (Smith 1953, p. 444). The Hindu mathematician Āryabhata (475 or 476-550) gave a rule for the sum of a geometric series that shows knowledge of the quadratic ...

Write a quadratic equation in the variable x having the given numbers as solutions. Type the equation in stadard form ax^2+bx+c=0 Solution 7, only solution Write a quadratic equation that has the given solutions. -3 and 6 Write a quadratic ...
If it's equal to zero, we immediately know that the solution is x=−b2x=−2b. If it's negative, then our equation has no real solutions and only complex solutions. The method of completing the square will work for every quadratic equation you can imagine. Above, we assumed that the...
