I like to use technology as an exploratory tool for students. Once students learn that sine is the ratio of the opposite side to the hypotenuse, show them the image below and have them use their TI-84 Plus CE to calculate the sine of the three angles (65°,75°and85°). Ask them: ...

2 taking root on both sides; x– ¼ = ±3/4 add ¼ on both sides x = ¼ ± ¾ therefore, x = ¼ + ¾ = 4/4 = 1 x = ¼ – ¾ = -2/4 = -½ to learn more about completing the square method, click here . using quadratic formula for the given ...
This one does not need the quadratic formula. rearrange and simplify: x2 = -20 x = ±√-20 = ±2 * i√5 x2 - 4x = -10 I'll check by completing the square: x2 - 4x + 4 = -10 + 4 (x - 2)2 = -6 x - 2 = 2 ± i√6 You got them both right!! Upvote •...

aSo let us see how to use this equation to solve a quadratic equation. We try the quadratic equation x2+ 21 = 10x. In order to use Proposition II-5, we rewrite this as 10x – x2= 21, or, factoring the left side, as (10 – x)x = 21. Comparing this to our formula above, ...
aWhere shall we meet? 我们在哪里将见面?[translate] aHow could you apply either of the two versions of the quadratic formula which we have considered to solve the equation x2= 5x + 14? 您怎么可能运用我们考虑解决等式x2= 5x + 14二次方惯例的二个版本之一?[translate]...
This is equal to the ABC-Formula for a = 1. However, this is easier to calculate. Numerical Example We take again x^2 + 8x + 15. Then: x^2 + 8x + 15 = (x+4)^2 -16+15 = (x+4)^2 -1 = 0. Then x = -4 + sqrt 1 = -3 or x = -4 - sqrt 1 = -5. ...
