The 2 roots of a quadratic equation are 3 and4.The equation is....................'

Answer»

Answer:

let the TWO roots are ALFA and beta

hence, alfa=3 and beta= 4

therefore,

alfa + beta= 3+4= 7

alfa × beta= 3×4=12

we know that

X2 - (alfa + beta)x + alfa× beta=0

hence substituting the values

x2 - 7X + 12=0 is the equation

(please take note that I have written 2 as SQUARE )
