Answer 1

Answer:

50y²-220y+210=0

10(5y²-22y+21)=0

5y²-22y+21=0

5y²-15y-7y+21=0

5y(y-3)-7(y-3)=0

(y-3)(5y-7)=0

y=3 or 7

32-34x+2x²=0

2x²-34x+32=0

2(x²-17x+16)=0

x²-17x+16=0

x²-1x-16x+16=0

x(x-1)-16(x-1)=0

(x-16)(x-1)=0

x=16 or 1

24x-2x²-70=0

-2x²+24x-70=0

-2(x²-12x+35)=0

x²-12x+35=0

x²-7x-5x+35=0

x(x-7)-5(x-7)=0

(x-7)(x-5)=0

x=7 or 5
