# Standard Form Quadratic Formula Ten Advantages Of Standard Form Quadratic Formula And How You Can Make Full Use Of It

Solve (2x^2 – 10x 3 = 0) application the boxlike formula.

Identify (a), (b) and (c). (a = 2), (b = -10) and (c = 3).

Substitute these ethics into the boxlike blueprint (x = frac{-b pm sqrt{b^2 – 4ac}}{2a}).

This gives:

(x = frac{–10 pm sqrt{(-10)^2 – 4 times 2 times 3}}{2 times 2})((-10)^2 = -10 times -10 = 100)

(x = frac{10 pm sqrt{100 – 24}}{4}). (–10 = 10) as two negatives accomplish a positive.

[x = frac{10 pm sqrt{76}}{4}]

(x = frac{10 sqrt{76}}{4}) or (x = frac{10 – sqrt{76}}{4})

(x = 4.68) (3 sf) or (x = 0.32) (3 sf)
