Question

What are the solutions of x2 + 5x − 24 = 0? Show all work for full credit.

Answer 1

do it by factorizing...

Answer 2

hint : split the middle term as
8x-3x

Answer 3

break 5x in two terms.

Answer 4

8x-3x

Answer 5

would it be

−b±/b^2 - 4ac
-------------
2a

Answer 6

thats using Quadratic formula...are u asked to use that ?
if not factorizing will be better approach

Answer 7

ya its asking for quadratic formula

Answer 8

Compare your quadratic equation with \(ax^2+bx+c=0\)
find a,b,c
then the two roots of x are:
\(\huge{x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}}\)

Answer 9

so, first tell me what u get for a,b,c.

Answer 10

a=x^2
b=5
c=24

Answer 11

no, 'a' is the co-efficient of x^2
here u have 1x^2
so a=.... ?

Answer 12

1^2
