1.	If alpha and beta are two zeroes of x2 - 3x+ 7 then find the value of alpha-1 +beta-1
Answer» Try to imagine the question in a different way.Solution:{tex}\\huge\\implies \\alpha-1+\\beta-1\\\\\\huge\\implies\\alpha+\\beta-1-1\\\\\\huge\\implies(\\alpha+\\beta)-2{/tex}{tex}\\huge\\implies Since,\\alpha+\\beta=-\\frac ba\\\\\\huge\\implies (given)\\space\\space a=1,b=-3\\\\\\huge\\implies Thus,(\\alpha+\\beta)-2\\implies-\\frac{-3}{1}-2\\\\\\huge\\implies 3-2\\implies\\boxed1{/tex}
