Question

(X-3) (x+3) = (x+5)2
$(x - 3)(x + 3) \geqslant (x + 5) { }^{2}$
​

Answer 1

Respuesta:

Explicación paso a paso:

(X-3) (x+3) = (x+5)2

X^2+3x-3x-9=x^2+10x+25

X^2-9=x^2+10x+25

-9=10x+25

-10x=25+9

-10x=34

X= -34/10

X= -17/5

Comprobación

(-17/5-3)(-17/5+3)=(-17/5+5)^2

((-17-15)/5)((-17+15)/5)=((-17+25)/5)^2

-32/5*(-2/5)=(8/5)^2

64/25=64/25
