Question

Medal

Part A: Write the expression x2 + 2x - 24 as a product of two linear expressions. Show your work and justify each step.

Part B: Rewrite x2 - 8x + 16 as a square of a linear expression

i only need help with part A though

Answer 1

@triciaal

Answer 2

part a is all i need help with really

Answer 3

A) During factoring, we want 2 linear expressions to equal the given quadratic expression. Thus, we find that (x+6)(x-4) would equal x^2+2x-24

B) (x-4)^2...

Mix a up as much as ya can :).

Answer 4

ok thanx

Answer 5

No prob.

Answer 6

@nathan917 thanks for your input
@SedateFrog712 let's do this systematically

Answer 7

ok

Answer 8

x2 + 2x - 24 =0
general form a = 1 b = 2 c = -24
a*c = -24
what are the factors of -24 that add up to +2?

Answer 9

use -12 and +2
x^2 -12x + 2x -24 =0
rewrite to group if necessary and factor each group

Answer 10

sorry 6 and -4

Answer 11

its ok

Answer 12

x^2 + 6x -4x -24 = 0
x(x + 6) -4(x + 6) =0
(x-4)(x +6) =0
x=4; x = -6

Answer 13

forget x =
question only asked for the factors

Answer 14

o ok it make allot more scene now thank you for explaining it to me

Answer 15

anyway the idea is that you do have steps to follow rather that mixing and matching to redo each time.

Answer 16

and you see the signs are important
