Question

form a quadratic equation if roots are -1 and 7​

Answer 1

Step-by-step explanation:

if roots are -1 and 7

let alpha= -1 and beta = 7

alpha +beta = -6

alpha × beta = -7

therefore to form quadratic equations

Formula is x^2 - (alpha + beta)x + alpha× beta = 0

therefore equation is x^2 +6x -7 =0
