לגורמים של הטרינום x+2x+1 הוא:

7) \( \quad 4 x^{2}-12 x+9=0 \) 8) \( (x-2)(x+3)=6 \)

Solve by completing the square. (Enter your answers as a comma-separated list. If there is no real solution, enter NO REAL SOLUTION.) \[ y^{2}+y-9=0 \] \( y=\square \)

Solve for \( x \) by completing the square: \[ x^{2}=-3 x+10 \] Determine the value of \( p \) if \( f(x)=x^{2}+p x^{2}-x+3 \) gives a remainder of 15 when divided by \( x-2 \).

Solve the system of equations by the substitution method. \[ \begin{array}{l}4 x+3 y=45 \\ x=4 y-3\end{array} \]

b) \( 15 x-(4 x-7)=95 \)
