Simplify the expression:
7 + -10c2 + 100
                                             
                                          
                                          
                                        
											 
											Simplify the expression:
7 + -10c² + 100
collect like terms:
7+100-10c²
107-10c²
If you meant, 7+ -10c² + 10c, then it can't be simplified further as there are no like terms.
