YOU USE THE QUATDRATIC FORMULA
M^2-40=0
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%28-0+%2B-+sqrt%28+0-4%2A1%2A%28-40%29+%29%29%2F%282%2A1%29+
x+=+%280+%2B-+sqrt%28+0%2B160+%29%29%2F%282%29+
x+=+%280+%2B-+sqrt%28+160+%29%29%2F%282%29+
x+=+%280+%2B-+sqrt%28+16+%29sqrt%2810%29%29%2F%282%29+
x+=+%280+%2B-+4sqrt%28+10+%29%29%2F%282%29+
x+=+%280+%2B-+2sqrt%28+10+%29%29+
