Question Help!<br><br> Factor the trinomial completely.<br><br> x squared + 2x -8

blsea [12.9K]

X^2 + 2x -8
The factors of 8 are 2 and 4, and to get 2x we need 2 and 4 to either add up to or subtract to result in 2.
4 - 2 = 2. We also know this is right because 4 x -2 = -8. So the answer is:
(x + 4)(x - 2)

Answer:

x = x = 9 ± $\sqrt{13}$ or x ≈ 12.61 or x ≈ 5.39

Step-by-step explanation:

x² - 18x + 68 Solve by completing the square.

x² - 18x = - 68

Now complete the square and add that number to both sides of the equation.

1/2 (of the coefficient of the x term)² = (1/2 · -18)² = 81 .

x² - 18x + 81 = -68 + 81

(x - 9) (x - 9) = 13 Now find the square root of both sides

$\sqrt{(x - 9)(x - 9)}$ = $\sqrt{13}$ Solve

x - 9 = ± $\sqrt{13}$ Solve for x

x = 9 ± $\sqrt{13}$

x = 9 + $\sqrt{13}$ or x = 9 - $\sqrt{13}$

x ≈ 12.61 or x ≈ x 5.39
