Answer:

Option B, z = 2

Step-by-step explanation:

Step 1: Factor

z^2 - 4z + 4 = 0

(z - 2)(z - 2) = 0

Step 2: Solve for z

z - 2 + 2 = 0 + 2 and z - 2 + 2 = 0 + 2

z = 2 and z = 2

Double root at z = 2

Answer: Option B, z = 2

FromTheMoon [43]

Answer: $t\in [\dfrac{1}{4},2]$

Step-by-step explanation:

Given

Inequality is $4t^2\leq9t-2$

Taking variables one side

$\Rightarrow 4t^2-9t+2\leq0\\\Rightarrow 4t^2-8t-t+2\leq0\\\Rightarrow 4t(t-2)-1(t-2)\leq0\\\Rightarrow (4t-1)(t-2)\leq0$

Using wavy curve method

$t\in [\dfrac{1}{4},2]$
