stepladder [879]

This is the function

${2x}^{2} - 2 {x}^{1} + 12$

Then factor 2 out

$2(x^2- x + 6) = 0$

Divide both side by two and use the quadratic formula to get the following

$(x - 3)(x + 2) = 0$

X=3 And x=-2 and don't forget to Chek them

If x = 4cosa and y = 5tana, find (x^2/16) - (y^2/25)

Cloud [144]

$x = 4 \cos(a)$

$\frac{x}{4} = \cos(a) \\$

$( { \frac{x}{4} })^{2} = ({ \cos(a) })^{2} \\$

$\frac{ {x}^{2} }{16} = {cos}^{2} (a) \\$

_____________________________________________

$y = 5 \tan(a)$

$\frac{y}{5} = \tan(a) \\$

$( { \frac{y}{5} })^{2} = ( { \tan(a) })^{2} \\$

$\frac{ {y}^{2} }{25} = {tan}^{2} (a) \\$

_____________________________________________

Thus ;

$\frac{ {x}^{2} }{16} - \frac{ {y}^{2} }{25} = \\$

${cos}^{2} (a) - {tan}^{2} (a)$
