Question

(x+5)(x-3) @Jelia97

Answer 1

do you need the graph?

Answer 2

This is for monomials

Answer 3

(x+5)(x-3) = x^2 + 2x - 15 = 16
The answer is 16

Answer 4

(x - 3)(x + 5) =
x² +5x -3x -15
x² +2x -15

Answer 5

2x^3-15?

Answer 6

Jelia is correct....answer is x^2 + 2x - 15...you can do it using the FOIL method

Answer 7

I haven't got to that chapter yet. Should I start on that one first?

Answer 8

That is up to you.

Answer 9

What would be the easiest ay to learn this?

Answer 10

FOIL method...do you want me to explain it to you ?

Answer 11

Yes

Answer 12

FOIL stands for First, Outside, Inside, Last

(x + 5)(x - 3)
F -- multiply first terms in each set...x * x = x^2
O -- multiply outside terms in each set....-3 * x = -3x
I -- multiply inside terms in each set...5 * x = 5x
L -- multiply last terms in each set...5 * -3 = -15

now put it all together...
x^2 - 3x + 5x - 15---combine like terms
x^2 + 2x - 15

Voila! Easy as that.
any questions ?

Answer 13

Omg that is so easy thank you :)

Answer 14

no problem...glad to help :)
