Factor completely

1 answer:

4 0

2.) 2x^2 - 3x - 14 = 0
2x^2 + 4x - 7x - 14 = 0
2x(x + 2) - 7(x + 2) = 0
(2x - 7)(x + 2) = 0

3.) x^2 + 7x = 18
x^2 + 7x - 18 = 0
x^2 - 2x + 9x - 18 = 0
x(x - 2) + 9(x - 2) = 0
(x + 9)(x - 2) = 0

4.) 9x^2 + 30x + 25 = 9x^2 + 15x + 15x + 25 = 3x(3x + 5) + 5(3x + 5) = (3x + 5)(3x + 5) = (3x + 5)^2

5.) x^2 - 14x + 49 = x^2 - 7x - 7x + 49 = x(x - 7) - 7(x - 7) = (x - 7)(x - 7) = (x - 7)^2

Find 3 consecutive even integers if their sum decreased by 10 equals -22

Orlov [11]

Three consecutive even integers can be represented by x, (x+2), and (x+4).

(x + (x + 2) + (x + 4)) - 10 = -22 Get rid of the parentheses
x + x + 2 + x + 4 - 10 = -22 Combine like terms (x + x + x) and (2 + 4 - 10)
3x - 4 = -22 Add 4 to both sides
3x = -18 Divide
x = -6
Check you work.

x = -6
x + 2 = -4
x + 4 = -2

(-6 - 4 - 2) - 10 = 22
-12 - 10 = -22

So, your three integers are -6, -4, and -2 .
