Verified answer

$\frac{4c^{2}+7c-2 }{1-16c^{2}}=\frac{4(c+2)(c-0,25)}{1^{2}-(4c)^{2}}=\frac{(c+2)(4c-1)}{(1-4c)(1+4c)}=-\frac{c+2}{4c+1}$

$4c^{2}+7c-2=0\\\\D=7^{2}-4*4*(-2)=49+32=81=9^{2} \\\\c_{1}=\frac{-7-9}{8}=-2\\\\c_{2}=\frac{-7+9}{8}=\frac{1}{4}\\\\4c^{2}+7c-2=4(c+2)(c-\frac{1}{4})=(c+2)(4c-1)$
