x^2-(α+β)+αβ = x^2 -7 +10 Jo isse phle answer ki thi wo glt solve kr di thi....yeh solution shi h dekh lo
Because sum of zero is given 7 means (alpha + bita )=7.and (alpha×bita)=10 that is product of zero
X^2 -7x+10

Deep Singh 6 years ago

x^2-(α+β)x+αβ X^2-(7+10)x+(7*10) X^2-17x+70 Therefore,p(x)=x^2-17x+70.
