Calculator Use
This online calculator is a quadratic equation solver that can resolve a second-order polynomial equation comparable to ax2 + bx + c = 0 for x, where a ≠ 0, the usage of the quadratic formula.
The calculator solution will show work the usage of the quadratic components to clear up the entered equation for real and sophisticated roots. Calculator determines whether or not the discriminant \( (b^2 - 4ac) \) is not up to, more than or equivalent to 0.
When \( b^2 - 4ac = 0 \) there is one actual root.
When \( b^2 - 4ac > 0 \) there are two real roots.
When \( b^2 - 4ac < 0 \) there are two complex roots.
Quadratic Formula:
The quadratic method
\( x = \dfrac -b \pm \sqrtb^2 - 4ac 2a \)
is used to solve quadratic equations where a ≠ 0 (polynomials with an order of 2)
\( ax^2 + bx + c = 0 \)
Examples the use of the quadratic methodExample 1: Find the Solution for \( x^2 + -8x + 5 = 0 \), the place a = 1, b = -Eight and c = 5, the use of the Quadratic Formula.
\( x = \dfrac -b \pm \sqrtb^2 - 4ac 2a \)
\( x = \dfrac -(-8) \pm \sqrt(-8)^2 - 4(1)(5) 2(1) \)
\( x = \dfrac 8 \pm \sqrt64 - 20 2 \)
\( x = \dfrac 8 \pm \sqrt44 2 \)
The discriminant \( b^2 - 4ac > 0 \) so, there are two actual roots.
Simplify the Radical:
\( x = \dfrac 8 \pm 2\sqrt11\, 2 \)
\( x = \dfrac 8 2 \pm \dfrac2\sqrt11\, 2 \)
Simplify fractions and/or indicators:
\( x = 4 \pm \sqrt11\, \)
which becomes
\( x = 7.31662 \)
\( x = 0.683375 \)
Example 2: Find the Solution for \( 5x^2 + 20x + 32 = 0 \), the place a = 5, b = 20 and c = 32, using the Quadratic Formula.
\( x = \dfrac -b \pm \sqrtb^2 - 4ac 2a \)
\( x = \dfrac -20 \pm \sqrt20^2 - 4(5)(32) 2(5) \)
\( x = \dfrac -20 \pm \sqrt400 - 640 10 \)
\( x = \dfrac -20 \pm \sqrt-240 10 \)
The discriminant \( b^2 - 4ac
Simplify the Radical:
\( x = \dfrac -20 \pm 4\sqrt15\, i 10 \)
\( x = \dfrac -20 10 \pm \dfrac4\sqrt15\, i 10 \)
Simplify fractions and/or indicators:
\( x = -2 \pm \dfrac 2\sqrt15\, i 5 \)
which turns into
\( x = -2 + 1.54919 \, i \)
\( x = -2 - 1.54919 \, i \)
