Hey friends kiran is here,
Today we learnt about sum of roots and product of roots. many students pasted the information about imajinari number . mr. p like it very much and gave them bonus points. they explained briefly mr. p also show us alrebra refresher .
The sum of roots formul :-
-b+(b^2-4ac)^1/2 + -b-(b^2-4ac)^1/2
/ 2a /2a
The product roots formulae:-
{-b+(b^2-4ac)^1/2 {-b-(b^2-4ac)
/2a} /2a}
Slove each equation and complete the table :-
Equation Roots Sum of roots Product of roots Value of a Value of b value of c
1. x^2+5x+6 = 0 x = -2, -3 -5 6 1 5 6
2. x^2-9x+20 = 0 x = 4 , -5 - 9 -20 1 -9 20
3. x^2 +8x = 0 x = 0 , -8 -8 0 1 8 0
The algebra assignment is due november 25.
have a great evening
bye friends
