This figure shows the procedure for constructing a
Yuri [45]
<span>In the question "This figure shows the procedure for constructing a" The correct answer is "bisector of an angle" (option C). To construct an angle bisector: Draw an arc that is centered at the vertex of the angle to intersect both sides of the angle. From the point of intersection of the previous arc and the both sides of the angle, draw two more arcs to intersect at a point. The radius for the two arcs must be equal. Then draw a straight line from the point of intersection of the later set of arcs and the vertex of the angle.</span>

Complete the steps to factor 56x2 – 8x – 7x + 1 by grouping.
konstantin123 [22]

The factorization of the polynomial 56x^2-8x-7x+1 is (8x-1)(7x-1)

Step-by-step explanation:

We need to Complete the steps to factor 56x^2-8x-7x+1 by grouping.

After grouping:

(56x^2-8x) + (-7x + 1)

Factor the GCF from each group.

8x(7x-1)-1(7x-1)\\

Use the distributive property.

(8x-1)(7x-1)

So, the factorization of the polynomial 56x^2-8x-7x+1 is (8x-1)(7x-1)

Keywords: factorization by grouping
