10X-22=(8X+8)^2
10X-22=64X^2+128X+64
64X^2+128X-10X+64+22=0
64X^2+118X+86=0
32X^2+59X+43=0
USING THE QUADRATIC EQUATION WE GET
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
X=(-B+-SQRT[B^2-4*A*C])/2A
X=(-59+-SQRT[-59^2-4*32*43])/2*32
X=(-59+-SQRT[3481-5504])/64
X=(-59+-SQRT-20230/64
X=(-59+-44.98i/64
X=-59/64+44.98i/64
X=-.92+.7i
X=-.92-.7i
