Determine the quadratic equation with roots

zvonat [6]

Answer:

$y=6x^2-5x+1$

Step-by-step explanation:

If the quadratic equation has a root at $\dfrac13$ then when $x=\dfrac13$ , $y=0$

$\implies x=\dfrac13$

$\implies 3x=1$

$\implies 3x-1=0$

If the quadratic equation has a root at $\dfrac12$ then when $x=\dfrac12$ , $y=0$

$\implies x=\dfrac12$

$\implies 2x=1$

$\implies 2x-1=0$

Therefore, $y=(3x-1)(2x-1)$

$\implies y=6x^2-5x+1$

Make x the subject! urgent help

Serhud [2]

Answer:

$x = \frac{n}{b - {t}^{2} }$

Step-by-step explanation:

I supposed that is a "n".

Steps as below:

${t}^{2} = b - \frac{n}{x} \\ b - \frac{n}{x} = {t}^{2} \\ - \frac{n}{x} = {t}^{2} - b \\ \frac{n}{x} = - ( {t}^{2} - b) \\ \frac{n}{x} = b - {t}^{2} \\ n = x(b - {t}^{2} ) \\ x(b - {t}^{2} ) = n \\ x = \frac{n}{b - {t}^{2} }$
