Question

25x^2+x-4 factorize by quadratic formula.. find x

​

Answer 1

Answer:

x=$\frac{-1+\sqrt{401} }{50}$  or  $\frac{-1-\sqrt{401} }{50}$

Step-by-step explanation:

25x²+x-4

here a=25; b=1; c=-4

D=b²-4ac

D= 1² - 4×25×(-4)

D=1+400

D=401

√D=√401

x=$\frac{-b\±\sqrt{D}}{2a}$

x=$\frac{-1+\sqrt{401} }{50}$  or  $\frac{-1-\sqrt{401} }{50}$
