Find below the list of all AP Board Class 8th Maths Chapter 11 Algebraic Expressions Ex 11.2 Textbook Solutions for PDF’s for you to download and prepare for the upcoming exams:

Question 1.
Complete the table:

Solution:

Question 2.
Simplify: 4y(3y + 4)
Solution:
4y(3y + 4) = 4y × 3y + 4y × 4
= 12y2 + 6y

Question 3.
Simplify x(2x2 – 7x + 3) and find the values of it for (i) x = 1 and (ii) x = 0
Solution:
x(2x2 – 7x + 3)
= x × 2x2 – x × 7x + x × 3
= 2x3 – 7x2 + 3x
= 3 × 3 – 1 × 3 – 3 × 1 + 1 × 1
=9 – 3 – 3 + 1 = 4
∴(a – b)2 = 4sq.units
[∵ (3 – 1)2 = 22 = 4]

(ii)

∴ (a – b)2 = a2 – 2ab + b2
Area of ABCD + Area of CYZS
= a2 – 2ab + b2
area of ABCD – area of BXYC – area of DCST + area of CYZS
= 5 × 5 – 2 × 5 – 2 × 5 + 2 × 2
= 25 – 10 – 10 + 4
= 9 sq.units
[∵ (5 – 2)2 = (3)2 = 9]

Question 4.
Add the product: a(a – b), b(b – c), c(c – a)
Solution:
a(a – b) + b(b – c) + c(c – a)
=a × a – a × b + b × b – b × c + c × c – c × a
=a2 – ab + b2 – bc + c2 – ca
=a2 + b2 + c2 – ab – bc – ca

Question 5.
Add the product: x(x + y – r), y(x – y+r), z(x – y – z)
Solution:
x(x + y – r) +y(x – y + r) + z(x – y – z)
= x2 + xy – xr + xy – y2 + yr + zx – yz – z2
= x2 – y2 – z2 + 2xy – xr + yr + zx – yz

Question 6.
Subtract the product of 2x(5x – y) from product of 3x(x+2y)
Solution:
3x(x + 2y) – 2x(5x – y)
=(3x × x + 3x × 2y)-(2x × 5x – 2x × y)
= 3x2 + 6xy – (10x2 – 2xy)
= 3x2 + 6xy- 10x2 + 2xy
= 8xy – 7x2

Question 7.
Subtract 3k(5k – l + 3rn) from 6k(2k + 3l – 2rn)
Solution:
6k(2k + 3l – 2m) – 3k(5k – l + 3m)
= 12k2+ 18kl – 12km – 15k2 + 3kl – 9km
= -3k2 + 21kl – 21km

Question 8.
Simplify: a2(a – b + c) + b2(a + b – c) – c2(a – b – c)
Solution:
a2(a – b + c) + b2(a + b – c) – c2(a – b – c)
= a3 – a2b + a2c + ab2 + b3 – b2c – ac2 + bc2 + c3
= a3 + b3 + c3 – a2b + a2c + ab2 – b2c – ac2 – bc2
