(x+5) (x+5)+(x-2) (x-2)=372
x²+5x+5x+25+x²-2x-2x+4=372
x²+10x+25+x²-4x+4=372
x²+6x+29=372
x²+6x+29-372=0
Final answer:
x²+6x-343=0

(X + 5)^2 + (X - 2)^2 = 372
(X + 5)(X + 5) + (X - 2)(X - 2) = 372
X^2 + 10X + 25 + X^2 - 4X + 4 = 372
2X^2 + 6X + 29 = 372
2X^2 + 6X = 372 - 29
2X^2 + 6X = 343
2X^2 + 6X -343
