Solve for the variable:<br> 1. (x-3)² = <img src="https://tex.z-dn.net/?f=x%5E%7B2%7D" id="TexFormula1" title="x^{2}" alt="x^{2}

Answer:

The answer to your question is:

1) x = 4

2) x = -2

Step-by-step explanation:

a) (x-3)² = x^{2} - 10x +25

x² - 6x + 9 = x² - 10x + 25

10x - 6x = 25 - 9

4x = 16

x = 4

(x+4)³ = x³ + 12x² - 16x

x³ + 3(x²)4 + 3x(16) + 4³= x³ + 12x² - 16x

x³ + 12x² + 48x + 64 = x³ + 12x² - 16x

48x + 64 = 16x

48x - 16x = -64

32 x = -64

x = -64/2

x = -2

Evaluate the expression StartFraction 12 minus 3 y Over 2 EndFraction plus y StartFraction 2 y minus 4 Over y EndFraction for y

vladimir1956 [14]

Answer: $\frac{31}{6}$

Step-by-step explanation:

Given

$\Rightarrow \frac{12-3y}{2}+y\frac{2y-4}{y}$

$\Rightarrow \frac{12-3y}{2}+\frac{y^2+2y-4}{y}$

Now for $y=3$

$\Rightarrow \frac{12-3\times 3}{2}+\frac{3^2+2\times 3-4}{3}$

$\Rightarrow \frac{3}{2}+\frac{9+6-4}{3}$

$\Rightarrow \frac{3}{2}+\frac{11}{3}$

$\Rightarrow \frac{9+22}{6}=\frac{31}{6}$
