Answer: 4x + 21 or 7 - 10x or -7x^2 - 3x + 7

not sure based on how the question is worded but it could be either 4x + 21 or 7 - 10x or -7x^2 - 3x + 7

Step-by-step explanation:

option 1

7x + 3(7-x)

= 7x + 21 - 3x

= 4x + 21

option 2

7 - (7x + 3x)

= 7 - 10x

option 3

7- (x(7x + 3))

7 - (7x^2 + 3x)

-7x^2 - 3x + 7

2x² - 5x+1 has roots alpha and beta. Find alpha⁴+beta⁴ without solving the equation.

shepuryov [24]

Answer:

Step-by-step explanation:

$\alpha+\beta=\dfrac{5}{2} \\\\\alpha*\beta=\dfrac{1}{2} \\\\\alpha^2+\beta^2=\dfrac{21}{4} \ (see\ previous\ post)\\\\(\alpha+\beta)^4=\dfrac{625}{16} \\\\=\alpha^4+\beta^4+4*\alpha^3*\beta+6*\alpha^2*\beta^2+4*\alpha*\beta^3\\\\=\alpha^4+\beta^4+4*(\alpha*\beta)(\alpha^2+\beta^2)+6*\alpha^2*\beta^2\\\\\alpha^4+\beta^4=(\alpha+\beta)^4-4*(\alpha*\beta)(\alpha^2+\beta^2)-6*\alpha^2*\beta^2\\\\= \dfrac{625}{16} -4*\dfrac{1}{2} *\dfrac{21}{4} -6*(\dfrac{1}{2})^2 \\\\$
