2.8^2=X^2+(X+1.6)^2
7.84=X^2+X^2+3.2X+2.56
2X^2+3.2X+2.56-7.84=0
2X^2+3.2X-5.28=0
2(X^2+1.6X-2.64)=0
USING THE QUADRATIC EQUATION WE GET
X=(-1.6+-SQRT[1.6^2-4*1*-2.64])/281
X=(-1.6+-SQRT[2.56+10.56])/2
X=(-1.6+-SQRT13.12)/2
X=(-1.6+-3.622)/2
X=(-1.6+3.622)/2
X=2.022/2
X=1.011 ANSWER.
X=(-1.6-3.622)/2
X=-5.244/2
X=2.611 ANSWER.
