Ques 10)  Factorise 121x2 – 88xy + 16y2

View Solution

To factorize the expression 121x2 – 88xy + 16y2, we can look for two numbers α and β such that α + β = -88 and αβ = 16 * 121.

The numbers that satisfy these conditions are -44 and -44 (-44 + -44 = -88 and -44 * -44 = 16 * 121 = 1936).

121x2 – 44xy – 44xy + 16y2

(121x2 – 44xy) – (44xy – 16y2)

11x(11x – 4y) – 4y(11x – 4y)

(11x – 4y)(11x – 4y)

(11x – 4y)2

Ques 11)  Factorise 1 – 6x + 9x2

View Solution

To factorize this expression, we need to find two numbers α and β such that α + β = 0.9 and αβ = 0.2

0.4x2 + 0.4x + 0.5x + 0.5

0.4 x(x+1) + 0.5 (x+1)

(0.4x + 0.5)(x+1)

Ques 13)  Factorise 100x2 – 80xy + 16y2

View Solution

We need to find two numbers α and β such that α + β = -80 and αβ = 16 * 100.

To factorize the expression, we split the middle term -80xy into two terms: -64xy and -16xy.

100x2 – 64xy – 16xy + 16y2

(100x2 – 64xy) + (-16xy + 16y2)

4x(25x – 16y) – 16y(25x – 16y)

(25x – 16y)(4x – 16y)

Ques 14)  Factorise x2y2 + 5xyz – 14z2

View Solution

To factorize this expression, we need to find two numbers α and β such that α + β = 5 and αβ = -14.

We can factorize the expression as follows:

x2y2 – 2xyz + 7xyz – 14z2

(x2y2 – 2xyz) + (7xyz – 14z2)

xy(xy – 2z) + 7z(xy – 2z)

(xy – 2z)(xy + 7z)

Ques 15)  Factorise 3x2y2 – xy2z – 24y2z2

View Solution

3(xy)2 – (xy)(yz) – 24(yz)2

To factorize this expression, we need to find two numbers α and β such that α + β = 1 and αβ = 72

3(xy)2 – 9(xy)(yz) + 8(xy)(yz) – 24(yz)2

3xy2(x – 3z) + 8y2z(x – 3z)

y2[3x(x – 3z) + 8z(x – 3z)]

y2(x – 3z)(3x + 8z)

y2(x – 3z)(3x + 8z)

Ques 16)  Factorise 11(a + b)2 + 21(a+b)(c + d) – 2(c + d)2

View Solution

To factorize this expression, we need to find two numbers α and β such that α + β = -6 and αβ = 9

11(a + b)2 + 22(a+b)(c + d) – (a+b)(c + d) – 2(c + d)2

11(a + b)[(a+b) + 2(c + d)] – (c + d)[(a + b) + 2(c + d)]

[(a + b) + 2(c + d)][11(a + b) – (c + d)]

(a + b + 2c + 2d)(11a + 11b – c – d)

Ques 17)  Factorise x2 + 4/x2 + 4

View Solution

Writing the above equation as:

x2 + (2/x)2 + 2 × x × (2/x)

Using the formula (a + b)2 = a2 + 2ab + b2, we get

(x + 2/x)2

Ques 18)  Factorise √3a2 + 5a + 2√3

View Solution

√3a2 + 3a + 2a + 2√3

√3a(a + √3) + 2(a + √3)

(√3a + 2)(a + √3)

Ques 19)  Factorise 4x2 + 1/16x2 + 1

View Solution

Rewriting the above equation as

(2x)2 + 1/(4x)2 + 2 × 2x × 1/4x

Using the formula (a + b)2 = a2 + 2ab + b2, we get

(2x + 1/4x)2

Ques 20)  Factorise s2 + r2 + 2sr + 1/4(s + r)2 +1

View Solution

Rewriting the above equation as

(s2 + r2 + 2sr) + 1/4(s + r)2 + 2 × (s + r)2 × 1/2(s + r)2

(s + r)2 + 1/{2(s + r)2} + 2 × (s + r)2 × 1/2(s + r)2

Using the formula (a + b)2 = a2 + 2ab + b2, we get

{(s + r) + 1/2(s + r)}2
