Step-by-step explanation:
Answer:
x=-7
Step-by-step explanation:
0.3(8-2x) - 1.2(2-3x) < -21
2.4 - 0.6x - 2.4 + 3.6x < -21
3x < -21
x < -7

[ a² + b² + 2ab = (a + b)² ]



so, the value of required expression is 6
[usually positive value is considered, but if asked the value can be either positive or negative]
