Every difference of squares problem can be factored as follows: a2 – b2 = (a + b)(a – b) or (a – b)(a + b). So, all you need to do to factor these types of problems is to determine what numbers squares will produce the desired results. Step 3: Determine if the remaining factors can be factored any further.
Answer:
10ˣ² +19ˣ + 6
Step-by-step explanation:
5ˣ(2x + 3) + 2 (2x + 3 )
10x² + 15x + 2(2x + 3 )
10x² + 15x + 4x + 6
= 10x² + 19x + 6

C.
Step-by-step explanation:
Required
Determine which option answers the question, correctly.
From the list of given options, only option c answers the question correctly.
This is shown below.
Represent
Length with l and Width with w, such that:

Area (A) is calculated as thus:

Substitute 7 + w for l and 18 for A.
This gives:

Open Bracket

Reorder

Subtract 18 from both sides


See that the above expression is a quadratic equation.
