1. x(x+5)=2
﻿﻿
>  (distribute x)   x²+5x=2
>  (transpose 2 to the other side)   x²+5x-2=0

2. (s+6)²=15
> s²+12s+36=15
> [transpose 15 to the other side] s²+12s+36-15=0
> [combine like terms] s²+12s+21=0

3. (t+2)²+(t-3)²=9

> (t+2)(t+2)+(t-3)(t-3)=9
> t²+4t+4+t²-6t+9=9
> [transpose 9 to the other side]   t²+4t+4+t²-6t+9-9=0
> [combine similar terms]   2t²-2t+4=0

4. (2r+3)²+(r+4)²=0

> 4r²+12r+9+r²+8r+15=0
>[combine similar terms]    5r²+20r+24=0

5. (m-4)²+(m-7)²=15

> m²-8m+16+m²-14m+49=15
> [transpose 15 to the other side]   m²-8m+16+m²-14m+49-15=0
> [combine similar terms]   2m²-22m+50=0

final answer: 2m²-22m+50=0 [mali pagkabasa ko sa una sorry]

[putek hirap nito isulat haha pero sorry kung magulo yung solution!!]

eh ito po ung no.2..and 4.. no. 2) (s+6)²=15....no.4)(2r+3)²+(r+4)²
ahmm...ung with solution nga po kung alam nio
aye ok sige wait :D
ok na po?? haha sana maintindihan niyo : D
