Find four consecutive integers, such that the product of the first and second integers minus 2 is equal to 3 times the product of the third and fourth integers.
@Mertsj
help please
Do you know how to represent 4 consecutive integers?
-6 -5 -4 -2?
-3**
No. x x+1 x+2 x+3
Now using that, you can write the equation.
(x+1)(x+2)(x+3)
x(x+1)(x+2)(x+3)
What is the product of the first and second ones?
-1, -2 ?
@Mertsj
x=first of four consecutive integers x+1= second of four consecutive integers x+2= third of four consecutive integers x+3 = fourth of four consecutive integers
What is the product of the first and second of the four consecutive integers?
I dont get it :( @Mertsj
can you show it to me please :( ?
@Loser66
@partygirl do you know how to solve this?
-2, -1,0,1 or -5,-4,-3,-2
how would I explain though @Arddhendu
Let the consecutive integers be x, x+1, x+2, x+3 As per the question x(x+1)-2=3(x+2)(x+3) x^2+x-2= 3x^2+15x+18 2x^2+14x+20=0 2(x^2+7x+10)=0 x^2+7x+10=0 x^2+2x+5x+10=0 x(x+2) +5(x+2)=0 (x+2)(x+5)=0 so, x+2=0 or x+5=0 so, x= -2 or -5 If x =-2, then the 4 consecutive integers are -2, -2+1, -2+2, -2+3 i.e., -2, -1, 0,1 If x=-5, then the 4 consecutive integers are -5, -5+1, -5+2, -5+3 i.e., -5, -4, -3,-2
is that everything ? @Arddhendu
yes
ok Im going to write it exactly how you wrote it
thank you so much ! @Arddhendu
