21. x² +9x - 22 Factors of cSum of Factors 7 7 ? ? 7 7 9 7

Eduardwww [97]

Answer:

$\large \begin{array}{| c | c |}\cline{1-2} \sf Factors\:of\:c & \sf Sum\:of\:Factors\\\cline{1-2} 1, -22 & -21 \\\cline{1-2} -1, 22 & 21\\\cline{1-2} 2, -11 & -9 \\\cline{1-2} -2, 11 & 9 \\\cline{1-2}\end{array}$

Step-by-step explanation:

Quadratic equation: ax² + bx + c = 0, where a ≠ 0

x² + 9x - 22

a = 1
b = 9
c = -22

Factors of c (-22):

1 × -22 or -1 × 22

2 × -11 or -2 × 11

Sum of factors:

1 + (-22) = -21 or -1 + 22 = 21

2 + (-11) = -9 or -2 + 11 = 9

Table:

$\large \begin{array}{| c | c |}\cline{1-2} \sf Factors\:of\:c & \sf Sum\:of\:Factors\\\cline{1-2} 1, -22 & -21 \\\cline{1-2} -1, 22 & 21\\\cline{1-2} 2, -11 & -9 \\\cline{1-2} -2, 11 & 9 \\\cline{1-2}\end{array}$

Hope this helps!
