X^2 +3x-4=0
(X+4)(x-1)=0 so x = -4 and x=1 are solutions

x² + 3x - 4 = 0 → (-4 = -1 * 4 or -2 * 2) → -1 + 4 = 3 and -2 + 2 = 0

(x - 1) (x + 4) = 0

x - 1 = 0 x + 4 = 0

+1 +1 -4 -4

x = 1 x = -4

Answer: 1, -4

Gre4nikov [31]

47 and 48 are the integers.

Step-by-step explanation:

Let,

x and x+1 be the integers, therefore, according to statement;

$x+(x+1)=95\\x+x+1=95\\2x+1=95\\2x=95-1\\2x=94\\Dividing\ both\ sides\ by\ 2\\\frac{2x}{2}=\frac{94}{2}\\x=47$

2nd Integer = x+1

2nd Integer = 47+1

2nd integer = 48

47 and 48 are the integers.
