Question

qual a forma fatorada de :
X²- 61x + 60=
X²+2X - 15=
X²+ 3x- 18=
X²- X- 42=

Answer 1

$x^{2} -61x+60=(x-1)(x-60) \\ \\ x^{2} +2x-15=(x+5)(x-3) \\ \\ x^{2} +3x-18=(x-3)(x+6) \\ \\ x^{2} -x-42=(x-7)(x+6)$

Answer 2

a) x² - 61x + 60 = (x -1) (x - 60)
b) x² + 2x - 15 = (x + 5) (x - 3)
c) x² + 3x - 18 = (x - 3)(x + 6) 
d) x² - x - 42 = (x - 7)(x + 6)
