Question

(x-3)(x-2)=24

Answer 1

\[x^2-5x+6=24\]
\[=x^2-5x-18=0\]
\[D=(-5)^2-4(1)(-18)=25+72=97\]
\[So x=(5+\sqrt{97})/2 or x=(5-\sqrt{97})/2\]

Answer 2

is there an easyer way to slove it

Answer 3

The easiest way is to use the scientific calculator to solve it.

Answer 4

i ment to put (x-3)(x+2)

Answer 5

No, that's not the way. You have to give that function to the form ax^2 + bx + c = 0

Answer 6

then use your scientific calculator to solve it

Answer 7

(x-3)(x+2)

Answer 8

(x-3)(x+2) = 24 <=> x^2 - 5x - 18 = 0

Answer 9

so the eqn becomes x^2-x-30=0
so, (x-6)(x+5)=0
=x = -5 or x=6
