write the sum and the product of the roots of 2x square+10x-5=0

\huge\red\bigstar\huge\mathcal{\underline{ \underline{SOLUTION}}}\bigstar

\boxed{}\\  \\

comparing the equation

2x² +10x-5=0 or x²+2x-(5/2)=0

with the equation

x²-(a+b)x+ab=0

we get

(a+b)= -2

therefore the sum of the roots is -2

ab=-(5/2)

therefore the product of the roots is -(5/2)
