Question

Solve the quadratic equation using quadratic formula :

15x^2 – 11x + 2 = 0​

Answer 1

Answer:

Using the quadratic formula

x = - b ± √b² - 4ac /2a

15x² - 11x + 2 = 0

a = 15 b = -11 c = 2

x = --11 ± √ (-11)² - 4(15)(2)/2(15)

x = 11±√121-120/30

x= 11±√1/30

x = 11 ± 1/30

x = 11 + 1/30 or x = 11 - 1/30

x = 2/5 or x = 1/3

Hope this helps.
