Answer:
There is 1 solution
Step-by-step explanation:
y = -3 (x+1) ^2
Using the zero product property
0 = -3 (x+1) ^2
Divide by -3
0 = (x+1) ^2
Take the square root of each side
sqrt(0) = sqrt( (x+1) ^2)
0 = x+1
Subtract 1 from each side
-1 =x
Check the picture below.
make sure your calculator is in Degree mode.
the answer is 6 and 9
6 x 2 is 12 and 12-3 is 9 added together they are 15
4
First, use the distributive property: 2x+16=4x+8
Second, move +8 to the other side(and turn it negative): 2x+8= 4x
Do the same for +2x: 8=2x
divide both sides by 2: 4=x
