Answer 1

Answer:

with splitting the middle twrm

Answer 2

Step-by-step explanation:

1)..x²+10x+16

=>x²+2x+8x+16

=>x(x+2)+8(x+2)

=>x+2=0;x+8=0

=>x= -2;x= -8

2)..x²+6x+8

x²+2x+4x+8

x(x+2)+4(x+2)

x+2=0;x+4=0

x= -2;x= -4

3)x²+9x+14

x²+2x+7x+14

x(x+2)+7(x+2)

x+2=0;x+7=0

x= -2;x= -7

4)x²+15x+50

x²+10x+5x+50

x(x+10)+5(x+10)

x+10=0;x+5=0

x= -10;x= -5

5)x²+12x+35

x²+5x+7x+35

x(x+5)+7(x+5)

x+5=0;x+7=0

x= -5;x= -7
