Question solve the following quadratic using the quadratic formula. \[ 5 x^{2}-3 x+1=0 \] Give your answer in the form \( \frac{a \pm b}{c} \), and use \( i \) in your answer if necessary.

4) Dado el dominio de cada función, determina el recorrido. \( \begin{array}{ll}\text { a. } f(x)=20 x \text { y } \operatorname{Dom}(f)=\{0,1,2,3\} & \text { b. } g(x)=-5 x \text { y } \operatorname{Dom}(g)=\{0,3,6,9\} \\ \text { c. } h(x)=x-3 \text { y } \operatorname{Dom}(h)=\{-2,-1,0,1\} & \text { d. } j(x)=3 x+4 \text { y } \operatorname{Dom}(j)=\{0,5,10,15\}\end{array} \)

A. \( 4 x^{2} y\left(x z^{2}+5 w x y+3\right) \).

Solve the equation by factoring. \[ x^{2}=7 x-12 \]
