Answer:
Step-by-step explanation:
y=-3/2(x+2)(x-4)
=-3/2(x²-4x+2x-8)
=-3/2(x²-2x-8)
=-3/2(x²-2x)-3/2×-8
=-3/2 (x²-2x+1-1)+12
=-3/2(x-1)²+3/2+12
=-3/2(x-1)²+27/2
Answer:
Let's solve your equation step-by-step.
3x−4=2x+1
Step 1: Subtract 2x from both sides.
3x−4−2x=2x+1−2x
x−4=1
Step 2: Add 4 to both sides.
x−4+4=1+4
x=5
Answer:
x=5
