Basis of the polynomial with degree less or equal 2

Can u explain me one thing. We have $P_2:= \{\text{all polynomial with degree}\leq 2\}$ and $U_0:=\{f \in P_2 \mid f(1)=0\}$ We have $f(1)=c_1+c_2+c_3$ (because every polymial has form of $ f(t)=c_1 +c_2\cdot t +c_3\cdot t^2.$ So we have as basis…
