Question

Find the value of 24xsq(1-2(and evaluate it for x =2

Answer 1

Let us multiply the given monomial and binomial as shown below:

24x

2

(1−2x)

=(24x

2

×1)−(24x

2

×2x)

=24x

2

−48x

3

Now, let us substitute x=2 in 24x

2

−48x

3

as follows:

24(2)

2

−48(2)

3

=(24×4)−(48×8)=96−384=−288

Hence, 24x

2

(1−2x)=−288 for x=2.
