to replace 2x we need +6x-4x
Answer:
6x - 4x
Step-by-step explanation:
x^2 + 2x – 24
We need to find out the factors that replace the middle term +2x
Constant term is -24
coefficient of middle term is +2
We need to find out two factors whose product is -24 and sum is +2
6 times (-4) = -24
6 + ( -4) = 2
So 6 and -4 gives us product -24 and sum +2
the middle term +2x can be written as 6x - 4x
d/4 + d/6=45/60 hours=3/4 hoursStep-by-step explanation:
3d+2d=12 x 3/4=9
5d=9
d=9/5 km ……………….
