2x^2 - 4x + 7
=>2(4)^2 - 4(4) + 7
=>23 ans
x = - 4
=>2(-4)^2 - 4(-4) + 7
=>55 ans

A protein has the sequence Met-Thr-X-Lys-Val where "X" indicates that the amino acid is unknown. Four new strains containing single-nucleotide substitutions in the gene encoding this protein were isolated and the corresponding mutant proteins were sequenced. The protein sequence of mutant 1 was Met-Thr-Arg-Lys-Val. The protein sequence for mutant 2 was Met-Thr-Ser-Lys-Val. The protein sequence of mutant 3 was Met-Thr-Leu-Lys-Val. The protein sequence for mutant 4 was Met-Thr-Gly-Lys-Val. Based on this information, what amino acid is corresponds to "X" in the wild type protein sequence.
