Question 319958
Write a quadratic equation using standard form ax^2+bx^+c=0 where 10 is the only solution.
FOIL
(x-10)(x-10) = x^2 - 20x + 100
:
Write a quadratic equation using standard form where 1 is the only solution.
FOIL
(x-1)(x-1) = x^2 - 2x + 1
:
Write a quadratic equation using standard form where
 {{{-sqrt(10)}}},{{{3sqrt(10)}}} are the only solutions.
FOIL
(x + {{{sqrt(10)}}})(x-{{{3sqrt(10)}}}) = x^2 - {{{3sqrt(10)}}}x + {{{sqrt(10)}}}x - 3(10) = x^2 - {{{2sqrt(10)}}}x - 30
