Answer 5

(x+3)(x+5)

=x^2 + (3+5)x + 3*5 [by using (a+b)(a+c) = a^2 + (b+c)a + bc]

=x^2 + 8x + 15

Answer 6

(+5536%) 78(#4575)

is that it???? LoL

Answer 7

Use the FOIL method.

F: First

O: Outter

I: Inner

L: Last

(x)(x) = x^2

(x)(5) = 5x

(3)(x) = 3x

(3)(5) = 15

x^2 + 5x + 3x + 15

-> Now combine any like numbers

5x + 3x = 8x

x^2 + 8x + 15

Now we evaluate:

x^2 + 8x + 15 = 0

What numbers make the expression equal to zero?

-3^2 +8(3) + 15 = 0

0 = 0

-5^2 + 8(-5) + 15 = 0

0 = 0

Final answer

x = -3, -5

Answer 8

Not a real question.

The long form is:

x^2 + 8x + 15

Answer 9

x^+5x+3x+15= x^+8x+15

Answer 12

say what?

Answer 13

the answer is :

x^2 +8x +15

Answer 14
