Question

1. Factorise using suitable Identities : a) ( y^2+ 3/2 ) ( y^2- 3/2 ) b) 4y^2 - 4y + 1 c) 4x^2 + 9y^2+ 16z^2 + 12 xy - 24 yz - 16 xz d) 2x^2+ y^2 + 8 z^2 - 2√2 x y + 4√2y z - 8 x z e) 27 p^2 - 1/216 - 9/2 p^2 +1/4 p f) 27 - 125 a^3 - 135 a + 225 a^2 g) 27 x^3 + y^3 + z^3 - 9 x y z

Answer 1

Answer:

Step-by-step explanation:

. 2 (x + z)-y

=2 (6+3)-8

=(2×9)-8

=18-8

=10

2. 5x - (y+2z)

=5×6 - (8 + 2×3)

=30 - (8 +6)

=30 - 14

= 16

3. x^2 + y^2 - 10z

6^2 + 8^2 - 10×336 + 64 -30

70

4. z^3 + (y^2 - 4x)

3^3 + 8^2 - 4×6

27 + 64 -24

70

5. y + xz/ 2

8 + (6×3)/3

8 + 18/3

8 + 6

14

6. 3y + x^2/z

24 + 36/3

24 + 12

=36 please mark it as abrainliest answer
