Step-by-step explanation:

$(x^{2} -3x+2)^{2} -4x+2\\(x^{2} -3x+2)(x^{2} -3x+2) -4x+2\\x^{4} -3x^{3} +2x^{2} -3x^{3} +9x^{2} -6x+2x^{2} -6x+4\\x^{4} -6x^{3} +13x^{2} -12x+4$

Answer:

Step-by-step explanation:

first of all we need to solve the inequalities

$3-x\geq 2\\\\3-x+x\geq 2+x\\\\3\geq2+x \\\\3-2\geq 2-2+x\\\\1\geq x\\\\x\leq 1$ (-∞,1] or ]-∞,1]

the second inequality is

$4x+2\geq 10\\\\4x+2-2\geq 10-2\\\\4x\geq 8\\\\\frac{4x}{4}\geq \frac{8}{4} \\\\x\geq 2$ [2,∞) or [2,∞[

so the answer is D
