Question

Which expression is equivalent to 6x2 – 19x – 55?
O (2x – 11)(3x + 5)
O (2x + 11)(3x - 5)
O (6x – 11)(x + 5)
O (6x + 11)(x - 5)

Answer 1

Answer:

(6x+11)(x-5)

$solution \\ {6x}^{2} - 19x - 55 \\ = {6x}^{2} - (30 -11)x - 55 \\ = {6x}^{2} - 30x + 11x - 55 \\ = 6x(x - 5) + 11(x - 5) \\ = (6x + 11)(x - 5)$

Hope this helps ...

Good luck on your assignment...

Answer 2

Answer:

$(6x + 11)(x - 5)$

Last Answer is correct.

Step-by-step explanation:

$6 {x}^{2} - 19x - 55 \\ 6 {x}^{2} - 30x + 11x - 55 \\ 6x(x - 5) + 11(x - 5) \\ (6x + 11)(x - 5)$

hope this helps you.
