Questiona) Factorise $x^{2}+9 x+14$. b) By sketching a graph, solve the inequality $x^{2}+9 x+14 \leq 0$.

Studdy Solution
The solution to the inequality is the interval where the quadratic is less than or equal to zero, which is:
$$-7 \leq x \leq -2$$
The factorization of the quadratic is:
a) $(x + 7)(x + 2)$
The solution to the inequality is:
b) $-7 \leq x \leq -2$
