Complete the steps to factor 56x2 – 8x – 7x + 1 by grouping.

group pairs of terms with common factors.
(56x2 – 8x) + (–7x + 1)

factor the gcf from each group.
8x(7x – 1) –1(7x – 1)

use the distributive property.
what is the factorization of the polynomial?

(8x – 1)(7x – 1)
(8x + 1)(7x – 1)
(8x + 7x)(1 – 1)

(8x-1)(7x-1) The question leaves you with the partially factored equation: 8x(7x-1) - 1(7x-1) look at the partially factored equation, you'll see that both terms have (7x-1) as one of their factors. take that (7x-1) as a factor and divide both terms by (7x-1), giving you (8x(7x-1) - 1(7x-1)) / (7x-1) The (7x-1) factors cancel out, leaving you with (8x - 1) So your 2 factors are (7x-1) and (8x-1). Looking at the available options, the only correct one is (8x-1)(7x-1)

A:  (8x-1) (7x-1)

Step-by-step explanation:

got it right on edge

good luck on the assignment

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
