Answer:
3 cm, 4 cm, 5 cm
Step-by-step explanation:
If the sum of the square of a number plus the triple of the same number equals eighteen, the required numbers are 3 and -6
Let the unknown number be x
The square of the number is expressed as x²
Triple of the unknown number will also be expressed as 3x
Taking the sum of both numbers and equating it to 18 will give;
![x^2 + 3x = 18\\x^2 + 3x - 18 =0](https://tex.z-dn.net/?f=x%5E2%20%2B%203x%20%3D%2018%5C%5Cx%5E2%20%2B%203x%20-%2018%20%3D0)
Factorize the resulting equation:
![x^2+3x -18=0\\x^2+6x-3x-18=0\\x(x+6)-3(x+6)=0\\(x-3)(x+6)=0\\x= 3 \ and \ -6](https://tex.z-dn.net/?f=x%5E2%2B3x%20-18%3D0%5C%5Cx%5E2%2B6x-3x-18%3D0%5C%5Cx%28x%2B6%29-3%28x%2B6%29%3D0%5C%5C%28x-3%29%28x%2B6%29%3D0%5C%5Cx%3D%203%20%5C%20and%20%5C%20-6)
Hence the required numbers are 3 and -6
