Question

aspa simple xsobre 2 + 13x + 42 = 0 xsobre 2 + 12x + 32 = 0 xspbre 2 + 15x + 54 = 0 3xsobre 2 – 10x + 3 = 0

Answer 1

Explicación paso a paso:

x + 7

+13x = (x+6)(x+7)=0 =>x+6=0 ^ x+7=0

x + 6 x=-6 x=-7

x +8

+12x =(x+4)(x+8)=0 =>x+4=0 ^ x+8=0

x +4 x=-4 x=-8

x +9

+15x =(x+9)(x+6)=0 =>x+9=0 ^ x+6=0

x +6 x=-9 x=-6
