1 Factor completely.
p2+7p+10 = (p + 5)(p + 2)
2 Factor completely.
x2+10x+16 = (x + 4)(x + 6)
3 Factor completely.
x2+7x−18 = (x + 9)(x - 2)
4 Factor completely.
x2−5x−24 = (x - 8)(x + 3)
5 Factor completely.
x2−3x−40 = (x - 8)(x + 5)
I'm sorry I just really need the points
The expression in part A is similar to the quadratic formula. So, it’s likely that complex numbers can help us solve quadratic equations that have imaginary solutions and that we would have labeled as having no solution if using only real numbers.
