How to find the value of the coefficient

Find The Value Of The Coefficient : Example Question #1

Give the coefficient of x2 in the product

(x+0.4)(x−0.2)(3x−0.7).

Possible Answers:

0.5

2.5

−0.1

1.3

0.7

Correct answer:

−0.1

Explanation:

While this problem can be answered by multiplying the three binomials, it is not necessary. There are three ways to multiply one term from each binomial such that two x terms and one constant are multiplied; find the three products and add them, as follows:

(x−−+0.4)(x−−−0.2)(3x−0.7−−−−)

x⋅x⋅(−0.7)=−0.7x2

(x−−+0.4)(x−0.2−−−−)(3x−−−0.7)

x⋅(−0.2)⋅3x=−0.6x2

(x+0.4−−−)(x−−−0.2)(3x−−−0.7)

0.4⋅x⋅3x=1.2x2

Add: −0.7x2+(−0.6x2)+1.2x2=−0.1x2.

The correct response is −0.1.
