The answer to your question is:

Step-by-step explanation:

12.-

x² - 6x = 5

x² - 6x + (3)² = 5 + (3)²

x² - 6x + 9 = 5 + 9

(x - 3)² = 14

13.- x² - 6x = 12

x² - 6x + (3)² = 12 + (3)²

x² - 6x + 9 = 12 + 9

(x - 3)² = 21

x - 3 = ±√21

x1 = √21 + 3 x2 = -√21 + 3

x1 = 7.58 x2 = -1.58

14.- 2x² - 24x = - 20 Divide by 2

x² - 12 x = -10

x² - 12x + (6)² = - 10 + (6)²

x² - 12x + 36 = - 10 + 36

( x - 6) ² = 26

x - 6 = ±√26

x1 = √26 + 6 x2 = -√26 + 6

x1 = 11.1 x2 = 0.9

What is the value of the expression x^2y–y+xy^2–x for x=4 and y=0.25?

stepan [7]

Answer:

0 (zero)

Step-by-step explanation:

${x}^{2} y - y + x {y}^{2} - x \\ = {4}^{2} \times 0.25 - 0.25 + 4 \times {0.25}^{2} - 4 \\ = 16 \times 0.25 - 0.25 + 4 \times 0.0625- 4 \\ = 4 - 0.25 + 0.25 - 4 \\ = 0 \\ \\ \purple {\boxed{ \bold{ \therefore \: {x}^{2} y - y + x {y}^{2} - x = 0}}}$
