Question

solve division method

Answer 1

1st : 3 (3xplus1) * (4xplus5) / ( 3x plus1)
FIRSTLY WE HAVE TO DIVIDE 3X PLUS 1 BY 3XPLUS1
SO , 3*1 (4X PLUS 5)
3 (4X PLUS 5 )
12X PLUS 15
ANS IS 12X PLUS 15

2nd : (15a-10) / 5
15a -10 upon 5
5 (3a-2)upon 5
AND CUTSHORT THE 5BY 5 SO,1
ANS : 3a-2

3 : (a square plus a - 56) / (a/8)
SO , (a square plus a minus 56) divide a/8

(a square plus a minus 56 ) * 8upon a

AND THEN MULTIPLY ALL NO. BY 8

8a square plus 8a minus 448 upon a

SO THE ANSWER IS 8 a square plus 8 a minus 448 upon a

Answer 2

3(3x+1)(4x+5)÷(3x+1)
=3(4x+5)
=12x+15 ans.
(15a-10)÷5
=15a/5-10/5
=3a-2 ans.

(a^2+a-56)÷(a+8)
={(a)^2+a(8-7)-56}÷(a+8)
=(a^2+8a-7a-56)÷(a+8)
={a(a+8)-7(a+8)}÷(a+8)
=(a+8)(a-7)÷(a+8)
=(a-7).ans...

(m^2+9m+20)÷(m+4)
={m^2+m(4+5)+20}÷(m+4)
=(m^2+4m+5m+20}÷(m+4)
={m(m+4)+5(m+4)}÷(m+4)
=(m+4)(m+5)÷(m+4)
=(m+4) ans..
