Answer» 3 ) Given : m^3 + 2m + a = 12, where m = 2.Therefore,m^3 + 2m + a = 122^3 + 2×2 + a = 128 + 4 + a = 12A = 0. 4) Given polynomial mx^2-2x+3mx 2 −2x+3we have to find the value of m if p(-1)=7 then find m ..p(X)=mx^2-2x+3P(x)=mx 2 −2x+3p(-1)=m(-1)^2-2(-1)+3p(−1)=m(−1) 2 −2(−1)+37=m+2+37=m+2+3m=2m=2Explanation: HOPE u like it..
