Question

find the roots of the polynomial square:
x^2 + 24 = –11x

Answer 1

answers
a)12,2
b)3,8
c)-8,-3
d)-12,-2

Answer 2

put all terms to one side of the equation, then factor the equation. 8(3)=24 and 8+3=11 so the factors are 8 and 3 and then the roots would be -8 and -3. So your answer is "c"

Answer 3

this is a simple quadratic and so you should factor it......faster then the quadratic formula.

Answer 4

you can use completing the square or the quadratic formula or just factoring :)

Answer 5

x^2+24=-11x is the same as x^2+11x+24=(x+3)(x+8) and if 0=(x+3)(x+8), well then the roots are x=-3,-8
