Answer 1

Answer:

(x+2) (15x-11)

Step-by-step explanation:

$$\begin{lgathered}15x^{2} + 30x -11x -22\\15x(x+2) - 11(x+2)\\(15x-11)(x+2)\end{lgathered}$$

$$\begin{lgathered}y^{2} -4y -2\\Using quadratic formula the two roots are (-b +\sqrt{b^{2}-4ac})/2a \\and \\ (-b -\sqrt{b^{2}-4ac})/2a\\Gives the following roots: 2+\sqrt{6} \\and \\2-\sqrt{6}\end{lgathered}$$
