Question

(x + 3) (x + 4) + 28x > (x + 5) (x + 7)

Answer 1

Respuesta:

(X+3)(X+4)+28X>(X+5)(X+7)

(X)^2+(3+4)X+(4×3)+28X>(X)^2+(5+7)X+(7×5)

X^2+7X+12+28X>X^2+12X+35

(1-1)X^2+(7+28)X+12>X^2+12X+35

35X+12>X^2+12X+35

(35-12)X+12>X^2+12X+35

23X+12>x^2+35

23x+12-35 > x^2

23x-23 > x^2

0 > x^2-23x+23
