Best ResponseYou've already chosen the best response.1This is a quadratic equation. It can be factored into two binomials. In pictures, you want to find values of x where the curve intersects the x axis. (see picture)

Best ResponseYou've already chosen the best response.0Factorise (split into brackets):\[c^2+3c+2=(c+2)(c+1)=0\]Then, you have two numbers that when multiplied together make 0, so one of them is zero. So, either:\[c+2=0=>c=2\]or\[c+1=0=>c=1\]
