Question

(x-1).(x+5)/3-(x+2).(x+5)/12=(x-1).(x+2)/4

Answer 1

Step-by-step explanation:

(x-1).(x+5)/3-(x+2).(x+5)/12=(x-1).(x+2)/4

x²+5x-x-5/3+x²+5x+2x+10/12=x²+2x-x-2/4

4x²+20x-4x-20+x²+5x+2x+10/12=x²+2x-x-2/4

4x²+x²+20x-4x+5x+2x-20+10/12=x²+2x-x-2/4

5x²+23x-10/12=x²+2x-x-2/4

5x²+23x-10/12×4=x²+x-2

5x²+23x-10/3=x²+x-2

5x²+23x-10/3-x²-x+2=0

5x²+23x-10-3x²-3x+6/3=0

5x²-3x²+23x-3x-10+6/3=0

x²+20x-4/3=0

i hope it will helps you
