Answer:
x = -7, 3
Step-by-step explanation:
×(3×-5)=(×-6)( ×-7)
3 x^2 - 5 x = x^2 - 7 x - 6 X + 42
3 x^2 - 5 x = x^2 - 13 x + 42
3 x^2 - x^2 - 5 x + 13 x - 42 =0
2 X^2+ 8 x - 42 =0
X^2 + 4 x - 21 =0
X^2 + 7 x - 3 x - 21=0
X ( X + 7 )- 3 ( X + 7)=0
(X + 7 )( x -3)=0
either , or,
x+7=0 x-3=0
x= -7 x=3
Hope it will help you.
