Answer:
y=0,y=7/5,y=-9/4
Step-by-step explanation:
12y(5y-7)(4y+9)=0
Using the zero product property
12y =0 (5y-7) =0 (4y+9)=0
12y/12 =0/12 5y-7 +7 =0+7 4y+9-9=0-9
y =0 5y = 7 4y = -9
5y/5 = 7/5 4y/4 =-9/4
y = 7/5 y =-9/4
No, they are not equivalent. The first term, -4 1/2 equals 4 whole units and one half unit. All negative. So it’s like you have someone 4 and 1/2 dollars.
The second term, (-4)1/2 means multiplying -4 times 1/2. Doing the multiplication for this gives you -4/2. Solving the division here is -2. It’s taking away 1/2 dollar 4 times.
I hope this helped. Happy to answer any questions you have.
