1) X²+5X-50=0

↠X² + 10X -5X -50 = 0

↠X(X+10)-5(X+10) = 0

↠(X-5)(X+10)=0

↠X = 5, -10

2)B²+6B-16=0

↠B² + 8B - 2B -16 = 0

↠B(B+8) -2(B+8) =0

↠(B-2) (B+8) =0

↠B = 2,-8

3)R²+6R+8=0

↠R²+4R+2R+8=0

↠R(R+4)+2(R+4)=0

↠(R+2)(R+4)=0

↠R=-2,-4

4) P²+5P+6=0

↠P²+3P+2P+6=0

↠P(P+3)+2(P+3)=0

↠(P+2)(P+3)=0

↠P=-2,-3
