if alpha and beta are roots of equation x square+5x+5=0, then equation whose roots are alpha +1 and beta +1 is wat?

Expert Answer:

The new equation is (x - (alpha + 1))(x - (beta +1)) = 0
so x2 - x(alpha + beta + 2) + (alpha.beta + alpha + beta + 1) = 0
x2 - x(-5 +2) + ( -5 + 5 + 1) = 0
x2 + 3x + 1 = 0
