Step-by-step explanation:
let the first consecutive integer=x
second consecutive integer=x+1
square of both Integers
x²+(x+1)²=145
x²+x²+1+2x=145 [by applying formula (a+b)²]
2x²+2x-144=0
by splitting middle term
2x²+ 18 x - 16 x-144 =0
2x(x+9)-16(x+9)=0
(2x-16)(x+9)=0
2x-16=0 or x+9=0
2x= 16. | x= -9
x= 16/2. |. (not possible) value)
x=8. |
hence,
first integer x =8
second integer X + 1 = 9
