Answer 2

Answer:

HEY MATE !!

HERE IS UR ANS ⤵️⤵️

i ) (2y+5)²

• 4y+25 (ans)

iii) (6x²-5y)²

• 36x²-25y (ans)

v) (6x-7) (6x+7)

• here, we have to use eqñ { (a+b) (a-b) }
• 6x²-7²
• 36x-49 (ans)

vii) (x+3) (x+7)

• (x+x) (+3+7)
• 2x+10 (ans)

ix) (xyz-4) (xyz-2)

• (xyz+xyz) (-4 -2)
• 2xyz-6 (ans)

ii) (xy + 3z)²

• 2xy+ 9z (ans)

iv) (0.4p - 0.5q)²

• (2/5p - 1/2q)²
• 4p - 2q (ans)

vi) (-a+c) (-a-c)

• (-a-a) (+c-c)
• -2a (ans)

viii) (4x+5) (4x-9)

• (4x+4x) (+5-9)
• 8x-14 (ans)

... HOPE THIS HELPS U ALMOST ...
