What is the factorization of the trinomial below -x^2 + 2x + 48
OlgaM077 [116]

For this case we must factor the following expression:

-x ^ 2 + 2x + 48

We take the sign "-" as a common factor of the expression, taking into account that:

- * - = +\\- (x ^ 2-2x-48)

To factor, we must find two numbers that, when multiplied, result in -48 and when added, result in -2. These numbers are -8 and +6.

-8 + 6 = -2\\(-8) * (+ 6) = - 48

Then, we factor the expression within the parenthesis as:

- ((x-8) (x + 6))

Answer:

- (x-8) (x + 6)

Solve x2 + 8x + 8 = 0 by completing the square. Which equation is used in the process?
garri49 [273]

x² + 8x + 8 = 0

x² + 8x + 8 + 8 = 0 + 8

x² + 8x + 16 = 8

x² + 4x + 4x + 16 = 8

x(x) + x(4) + 4(x) + 4(4) = 8

x(x + 4) + 4(x + 4) = 8

(x + 4)(x + 4) = 8

(x + 4)² = 8
