Question

Find the real. values of x for which 15x² - 11x-14 is positive​

Answer 1

Answer:

(5x-7)(3x-2)

because 21-11 = 11

Answer 2

Answer:

Step-by-step explanation:

Assuming,

15x²-11x-14=0

By quadratic formula,

x = 11±√-11²-4(15)(-14) ÷ 2(15)

x = 11±√121+840 ÷ 30

x = 11±√861 ÷ 30

x = 11+√861 ÷ 30 or 11-√861 ÷ 30

(√861 = √3 · √7 · √41)
