Answer with solution​

Answer 1

Answer:

$x + \frac{1}{2} = 0 \\ x = - \frac{1}{2} \\ p(x) = { x}^{3} - 4 {x}^{2} + 12x + 7 \\ \\ p( - \frac{1}{2} ) = { (- \frac{1}{2} )}^{3} - 4 {( - \frac{1}{2}) }^{2} + 12( - \frac{ 1}{2}) + 7 \\ \\ = - \frac{1}{8} - 4 \times \frac{1}{4} - 6 + 7 \\ \\ = - \frac{1}{8} \\ \color{blue}\rightarrow (b)\:is\: correct \\ \\\red{\mathfrak{ \large{\underline{{Hope \: It \: Helps \: You}}}}} \\ \blue{\mathfrak{ \large{\underline{{Mark \: Me \: Brainliest}}}}}$
