Answer For Solving Quadratic Equations By Completing The Squares X\Xb2-2x=3 And S\Xb2+4s-21=0

Answer for solving quadratic equations by completing the squares x²-2x=3 and s²+4s-21=0

 

Answer:

X²-2x=3

x²-2x-3=0

(x-3)(x+1)=0

x-3=0

x=3

x+1=0

x=-1

x=3, x=-1

s²+4s-21=0

(s+7)(s-3)=0

s+7=0

s=-7

s-3=0

s=3

s=-7, s=3
