Question

Socorro (X+2) (x+3) +15x +8

Answer 1

.
Ola Gabs

(x + 2)*(x + 3) + 15x + 8 = 0

x² + 5x + 6 + 15x + 8 = 0

x² + 20x + 23 = 0

delta
d² = 20² - 4*23 = 308
d = 2√77

x1 = (-20 + 2√77)/2 = -10 + √77
x2 = (-20 - 2√77)/2 = -10 - √77

Answer 2

(X+2) (x+3) +15x +8

x² + 3x + 2x + 6 + 15x + 8

x² + 3x + 2x + 15x + 6 + 8

x² + 5x + 15x + 14

x² + 20x + 14
