Find the discriminant to determine the number of roots, then solve the quadratic equation using the quadratic formula.

2x^2+7x-4=0


Sagot :

[tex]2x^2 + 7x -4=0 \\<=> 2x^2+8x-x-4=0 \\<=>2x(x+4)-(x+4)=0\\<=>(x+4)(2x-1)=0\\<=> x+4=0 /or/ 2x-1=0\\<=>x=-4/or/x=\frac{1}{2}=0.5[/tex]

ok done. Thank to me :>
