Answer 10

Teach me how to solve this cuz i never solve like this equation before

Answer 11

the number of zeroes is determined by the degree of the polynomial

the value of the zeroes is a different story

Answer 12

Did you get it?

Answer 13

\[f \left( x \right)=8x^3+14x^2+11x+3\]
\[=8x^3+4x^2+10x^2+5x+6x+3\]
\[=4x^2(2x+1)+5x(2x+1)+3(2x+1)\]
\[=(2x+1)( 4x^2+5x+3) \]
