so in the question we have to find the value of α+β which is equal to -b/c
and product of zeroes = c/a and product of zeroes =αβ so αβ = c/a
in the question we have to find the value of : α+β+αβ
so we can also write α+β= - b/a and αβ = c/a
so we get - b/a + c/a
I hope you can understand now
yes thank s
it's okay

here we can factorise it as
x^2+2x+5x+10=0
×(×+2)+5(×+2)=0
(×+2)(×+5)=0
so eitherx=-2or-5
x^2+2x+5x+10=0
×(×+2)+5(×+2)=0
(×+2)(×+5)=0
so eitherx=-2or-5
