EXPLANATION.

Factorizes.

⇒ 4a² - 10a - 15.

As we know that,

⇒ D = Discriminant Or b² - 4ac.

⇒ D = (-10)² - 4(4)(-15).

⇒ D = 100 + 240.

⇒ D = 340.

⇒ α = - b + √D/2a.

⇒ α = -(-10) + √340/2(4).

⇒ α = 10 + √340/8.

⇒ α = 10 + 2√85/8.

⇒ α = 2(5 + √85)/8.

⇒ α = (5 + √85)/4.

⇒ β = - b - √D/2a.

⇒ β = -(-10) - √340/2(4).

⇒ β = 10 - √340/8.

⇒ β = 10 - 2√85/8.

⇒ β = 2(5 - √85)/8.

⇒ β = (5 - √85)/4.

                                                                                                                     

MORE INFORMATION.

Conjugate roots.

(1) = If D < 0.

One zeroes = α + iβ.

Other roots = α - iβ.

(2) = If D > 0.

One roots = α + √β.

Other roots = α - √β.
