s²+45-21=0 how to solve this​

Answer:I'm assuming it's 4s not 45 lol.If s²+45-21=0= s²+24=0Anyways if: S²+4s-21=0Step-by-step Explaination:= s² + 4s = 21. (we transposed -21 so it becomes positive 21 on the other side)= s² + 4s __ = 21 (always divide 4s by 2) ↪️ 4÷ 2 = 2 (ito gagamitin para sa standform) ↪️2² = 4 (ito na ung sa blank)= s² + 4s + 4 = 21 + 4= (s + 2)² = 25 (basta kapag stand form always use ung sagot after i divide sa 2 , aka ung 2² pero tatangalling lng ung (²) nya )= (s +2)² = 25= √(s+ 2)² = √25 = (s+2) ± 5POSITIVE: s + 2 = 5 (transpose 2)s = 5 -2s = 3NEGATIVE:s + 2 = -5 (transpose 2)s= -5 -2s = -7HOPE IT HELPS! PERFECT KANA YAY! ^^ (just copy the solution sunod sunod yan. kahit ung may arrow para kumpleto. itapat mu lng sa baba ng 4s)
