Question

solve by quadratic formula 2x square+x-4​

Answer 1

Answer:

x = -1 + √33 / 4

x = -1 + √33 / 4 x = -1 - √33 / 4

Step-by-step explanation:

From Question ,

a = 2

b = 1

c = -4

D = b²- 4ac

D = (1)² - 4(2)(-4)

D = 1 + 32

D = 33

Formula = -b + √D / 2a , -b - √D / 2a

x = -1 + √33 / 4 , -1 - √33 / 4
