Question

como puedo factorisar x2 +8/2×+15/5=0, 4×2-16×-10=0, ×2+5/3×+4/9=0, (×+2/3×)(×+5/2)=0, (2×-3)(2×-5)=0, (×+1/3)(×+3/4)=0​

Answer 1

Explicación paso a paso:

x² +8/2×+15/5=0, equivale a x²+ 4x+3=0

(x+3)(x+1)

4x²-16×-10=0,

podrías verificar que esté bien escrita?

ײ+5/3×+4/9=0,

(x+4/3)(x+1/3)/

(×+2/3×)(×+5/2)=0,

(x²+2/3x²)(+5/2x+10/6x)= 5/3x²+ 25/6x

(2×-3)(2×-5)=0,

(4x²-6x)+(-10x+15)= 4x²-16x+15

(×+1/3)(×+3/4)=0

(x²+1/3x)(3/4x+1/4)=x²+13/12x+1/4
